Preparation Of 0.50M Hcl & 0.0250M Na2co3 Solution. Help by Careartrust: 12:09pm On Dec 08, 2017 |
I want to prepare the following solutions for titration; 0.50 Mol/dm3 HCl and 0.0250 mol/dm3 Na2CO3 (sodium trioxocarbonate(V) Chemistry gurus please help. What is amount of HCl that can be dissolved in a certain volume of water. Also, what is the amount of sodium trioxocarbonate (gram) that can be dissolved in certain amount of water. Thanks |

@ Op go to play store and download molarity calculator. I believe it can solve your problem. |

It's simple if I remember my chemistry correctly (volumetric analysis). Using the formula Number of moles= Concentration (C, in mol/dm3) * Volume (in cubic decimeters,dm3) . From your question, the concentration of HCL required is 0.5M. Remember, number of moles (n) = mass/molar mass. Therefore, we can rewrite the formula (above) as: Mass/molar mass = C × V. Molar mass of HCL = 1 + 35.5= 36.5g/mol Since the concentration required is 0.5M, it means the volume is in dm3 which is also equivalent to a litre. Consequently, our volume is 1dm3 or 1 litre. what's left is the mass of HCL. Thus, the mass of HCL required to give us 0.5M of HCL solution = molar mass of HCL× concentration × volume = 36.5 × 0.5 × 1 = 18.25g. In sum, we need to dissolve 18.25g of HCL in 1 litre of water (or any solution specified). Please, follow suit and tackle that for sodium trioxocarbonate (IV). Cheers. |

YemziAdez: Thanks dear, I have also worked it out with the app someone mentioned above and it's giving me the same thing. However, I still need some clarification specifically about the acid(HCl). You know that the acid is in liquid state and should be measured using measuring cylinder? Question: How do I measure it since the value you got above is in grams (36.5g) |

Careartrust: Careartrust: Careartrust: convert the gram to ml ...hint:1000g=1l 1000ml=1L Guess u want to do some sort of physiochemical analysis right? |
