Solubility of salts in water.

Solubility Rules

1) All salts of sodium,Potassium and ammonium are soluble in water.
2) All trioxonitrate (V) salts are soluble in water.
3) All chlorides are soluble in water; except those of Lead, mercury and silver that are insoluble in water.
4) All tetraoxosulphate(VI) salts, are soluble in water ; except those of lead and barium. Calcium tetraoxosulphate (VI), CaSO 4 is only slightly soluble in water.

5) All trioxosulphate (IV) salts are insoluble in water;except those of sodium,Potassium and ammonium that are soluble.

6) All trioxocarbonate (IV) salts are insoluble in water; except those of sodium,Potassium and ammonium that are water-soluble.

7) All sulphides, S2- are insoluble in water; except those of sodium,Potassium and ammonium that are soluble.

8 ) All acid salts are soluble in water.

Note:
1) Gases, such as ammonia,NH3 and Hydrogen Chloride, HCL are highly soluble in cold water. Infact, they react with water.Their aqueous solutions are therefore used as laboratory reagents.

2) Gases such as SO2 , NO2 , CL 2 , H2 S , N2O and CO2 are fairly soluble in water; hence, they are not collected over cold water during their laboratory preparations. H2S is collected over warm water.

3) Other gases such as O2 , N2 , H2 and CO are only slightly soluble in water;they can be collected over water.

If the cerebellum of a person is slightly
damaged, which of the following will be
impaired?
(a) vision
(b) walking
(c) Digestion
(d) Breathing

Answer :B (walking)

Reason
Cerebellum, sometimes called the little brain , lies below the back of the cerebrum. It is oval in shape and consists of two hemispheres. It is less convoluted than cerebrum and are shallower and less irregular (more or less parallel) than those of cerebrum. The surface of cerebellum is covered with grey matter , while the inner side is composed of white matter. It is connected to the semi-circular canals of the ears.

Functions of the Cerebellum
1) It is concerned with the balance and positioning of the body, it receives impulses from semi-circular canals of the ears, through the vestibular nerve fibre.
2) It is the coordinator of various actions of muscles in voluntary responses such as walking, talking and sitting.

Charring of sugar occurs when it is
(a) reduced

(c) dehydrated

Answer: C

Reason
Charring of sugar is the dehydration of sugar either by heating it in the abscence of air or by heating it strongly with concentrated tetraoxosulphate(VI) acid to produce a black mass of carbon(known as char) and water.

Effervescence occurs when water comes
in contact with
(a) calcium
(b) copper
(c) sulphur
(d) lead

Answer: A (Calcium)

Reason
Potassium,sodium or calcium metal reacts with cold water to liberate hydrogen gas and giving an alkaline solution. However, the reaction with potassium or sodium is very violent.

Reaction of cold water with calcium metal
When a small piece of calcium metal is placed in a beaker of cold water,it sinks. A boiling tube full of water is then inverted over it and the metal dissolves with an effervescence or evolution of an odourless and colourless gas which is hydrogen. Hydrogen can be collected by upward delivery or downward displacement of air;since it is less dense than air being the lightest known gas.
As the calcium dissolves, a white suspension of calcium hydroxide, which is slightly soluble in water is formed. Hence, if the water in the beaker is initially coloured with a few drops of methyl orange , the solution changes from orange to yellow ....and if phenolphthalein is used, the colour change is from colourless to pink. This is because the resulting solution is alkaline.

Equation of the reaction.
Ca(s) + 2H 2 O(L) ----> Ca(OH) 2 + H 2

What are the products of the reaction
between ethyl ethanoate and ammonia?

Answer
When ammonia is bubbled through an alkanoate(ester), the corresponding amide and alkanol are produced. This is known as ammonalysis.
Ammonia reacts with ethylethanoate to produce a mixture of ethanamide and ethanol.

Equation of the reaction:
CH3COOCH2CH3 + NH3 ------> CH3CONH2 + CH3CH2OH
Re: UI 2018/2019 Admission Thread by DrBESTJC(m): 7:13am On Jul 19, 2018

The products of photochlorination of
ethanoic acid are?

Answer

Substitution Reactions in Alkanoic Acid.

Halogenation Reaction
When chlorine or bromine gas is passed into a mixture of an alkanoic acid (except methanoic acid) and a small amount of phosphorus in the presence of sunlight, 2-chloroalkanoic acid or 2- bromoalkanoic acid is formed.
The photochlorination of ethanoic acid produces 2-chloroethanoic acid and Hydrogen Chloride gas.

Equation of the reaction is:
CH3COOH + CL2 ----> CLCH2COOH + HCL

Note:
Substitution occures on the carbon directly attached to the carboxyl carbon (i.e. The alpha-carbon atom ) .

Which of the following compounds is
not obtained by polymerization?
(a) Plastic
(b) Polythene
(c) Petroleum
(d) Cellulose

Answer: C(Petroleum)

Reason:

1) Plastics
Plastics are polymers whose molecules can slide over one another when stretched, with the molecules remaining in their new positions when the stretching force is removed, i.e. for the material to become deformed.
Plastics of all kinds are synthetic polymers. They are light, soft or hard, flexible,tough and with great tensile strenghts. They are water proof, resistant to chemicals and heat. Plastics are non-biodegradable ; hence, plastic wastes usually accumulate in the soil and pollute the environment.

2) Types of Plastics
A) Thermoplastics
Thermoplastics are polymers that can be softened or melted when subjected to heat or pressure, and can be remoulded into any shape. For such polymers, their plasticity (plastic property) increases as the heat or pressure applied increases. Polyethene is an example of a thermoplastic.

B) Thermostats
Thermostats are polymers that cannot be softened or melted by heat or pressure. Once formed,they become set(rigid) and cannot be remoulded again. An example is polychloroethene(PVC).

3) Petroleum
Petroleum or crude oil occurs as a dark brown viscous liquid with unpleasant smell. It must have been formed millions of years ago by the decay and decomposition of marine organisms(plants and animals) after being subjected to high temperature and pressures in the abscence of air, and then trapped in porous rocks deep down the earth's crust, together with natural gas.

4) Cellulose
Polysaccharides are polymerisation products of thousands of molecules of monosaccharides(the hexoses). They include:
- Starch
- Cellulose
- Glycogen(animal starch)
- Inulin.
Cotton fibers are the purest form of cellulose.Nearly 90% of the cotton fibers are cellulose,making it nature's most abundant polymer.

From the above discussions,it is obvious that petroleum is not a product of polymerisation
