My Secondary School Chemistry Students Made This Salt by Oduok(m): 11:50am On Nov 09, 2021 |
The attached picture made my day. A group of SS2 students in one of the schools I visit to teach Chemistry came excitedly, "Sir, we have produced our own salt. We would not buy salt again in the market." I taught them in SS1 SEPARATION TECHNIQUES that you can obtain salt (NaCl) by evaporating sea water to dryness. The students now secretly arranged for one of them to visit Ibeno water and get sample of the seawater which they evaporated to dryness and here comes our locally made salt. Qualitative Analysis: The salt produced on exposure to air was found to be deliquescent - attracts water from the atmosphere to dissolve itself. It dissolves completely in water. The solution of the salt gave white precipitate when tested with solution of silver nitrate, the precipitate was insoluble in nitric acid (confirmatory test for chlorides) This indeed is very rewarding as it has been my expectation to help this young minds to begin now to figure out ways of harnessing our natural resources. While I will continue with the work of purifying the product at my private technical center, I have advised them that the salt need to be purified to remove carbonates and other non-sodium halides etc. We would in the present state use the salt as preservative for our emulsion paint, we would use it for laboratory test for chlorides and to demonstrate removal of hardness of water (water softening by ion exchange). My philosophy of high school chemistry is to let them understand the theory, carry out the laboratory practicals, and apply the knowledge to do mini projects. 326 Likes 32 Shares

You’re a brilliant man. I’m something of a genius myself too. But tell this to the average individual and they’d misunderstand you. I’m thankful for the woman that birthed me for the opportunity and wisdom she imbibed in me. Unfortunately she’s an “out of school” housewife. I remember one Saturday evening after I had my worst result in school, and then I came back with my report card, and after consoling me, she was forced to tell me her story. Let me quote her verbatim. She said “I wish I had the chance at pursuing my academics to this practical level. But in our society then, it was unlike today. It was difficult for us women. My father—who is your Grandfather, refused to send me to school because he thought ‘women preserved their values, while men created it.’ That is why the average woman is more desirable and valuable than the average man. I was barely concerned about succeeding in school. I just wanted to go to school because schooling was what at least one girl in each family did at that time. And I was fortunate that your aunties—my sisters, singled me out to go. Because at that time they had boyfriends, and their boyfriends would laugh at them if they found out that they sat down with children for hours, in a small classroom, merely looking at a blackboard.” She concluded by saying; “Success isn’t a lifestyle choice for ANY man. It’s a matter of life and death. On the other hand, look around you; It’s a lifestyle choice only for SOME women. A woman who fails at career or academia can just simply give up and become a wife, a lover or choose to become a mother like in my case. She would now suddenly be wanted for who she is, or what she has become. But tell me, who is interested in a man who is a loser? NOBODY. What can he make out of his unfortunate situation? Misery. More misery until the end of his days. Pursue your education like your whole life depends on it, because someday you’d realise your whole life really depends on it.” I almost teared up after this conversation. You have no idea how motivated I became and where it got me today. I wish she had the opportunity I had. 106 Likes 12 Shares |

Beautiful. The challenge of our education philosophy is the regurgitation of knowledge, rather than exploration. The key part for me is sowing the seed (idea), and helping to water it(alternate use of the salt). Keep inspiring these minds bro 4 Likes |
