They are apparently smarter than you... So they know that already.

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.

you're right sir, but i pity the parent as they both have high BP, what if something happens to them on hearing this. But on a second thougit she never considered me when she did this to me. You need to see how they were busy disturbing me & even coming to my house when i got her pregnant.

Please who can design and develop football prediction website

Another police station was attacked this morning
Which makes it 3 this week
By men who dance around the law
With their guns speaking out
