It's not pure yet!


Kudos teacher!
Sure. Not yet to be consumed. Still need refinement

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.
Tell them not to cook with it. Don't trust students

Mr Odouk

Sir
I need a favour from you. I'm a chemistry teacher (ss2 &ss1) I just got into the profession. But writing lesson plans has being an obstacle..

I don't know if your can assist me here.

Just mix acid plus base you get basically salt and water.

Even if you are Albert Einstein, don't in your life teach in a private school in Nigeria

These school owners are dubious and criminal minded
Never accept a teaching job that pays below 100k.

That salt is not safe for consumption unless it is purified. Unfortunately purification techniques is not taught in secondary schools. Only Chemistry major could perform such cool

For yahoo boys, the oga kpatakpata of them all is Buhari/Tinubu APC

1. APC scam Nigerians 2times (2015 and 2020) and they want to scam Nigerians again in 2023. God forbid.

2. APC made.fake promises
$1 under corruption - 180 naira
$1 under integrity - 575 naira

1 loaf of bread under corruption - 250 naira
1 loaf of bread under integrity - 600 naira

.......and the list goes on

@Deji Adeyanju

3. Osibanjo's APC scams Nigeria again:
Yemi Osibanjo says he is doing school feeding.
He has been doing school feeding for 6 years now.
Meaning the VP has been doing school feeding since when the 11 year old (who stole yam) was 5 years old.
If truly school feeding exist, this 11 years old would have been in school eating.

Meanwhile over 700million is spent on school feeding daily, over the past 6 years.

........but corrupt thieves like Osibanjo, are looting the money in the name of school feeding and the hungry police officer is charging a hungry minor to court for stealing food.

Today he has the guts to talk about reducing cost of governance.

Shame on this useless Fulani FG representative.

4. North APC scams Nigerians every day
What Do Northern States Really Want ?

1. Restructuring, NO
2. VAT collection by states, NO
3. Ranching, NO
4. Zoning or rotational Presidency, NO
5. Creation of state police, NO
6. True Fiscal federalism, NO
7. Electronic transmission, NO
8. Declaration of Boko Haram, bandits terrorist group, NO
9. Anti-open grazing, NO
10. Cattle tax, NO
11. National Conference, NO
12 Referendum, NO
13. Regional self-rule, NO
14. Constitutional review, NO
15. Biafra Republic, NO
16. Oduduwa Republic, NO
17. Middle Belt Region, NO
18. Social media freedom, NO

5.I want to know the landlord of Aso Rock. Fulani FG has been paying billion naira rent for aso rock, who is the landlord?

When the want to loot, they do horrible projects, but when they want to actually do something, they borrow outrageous amount.

Is aso rock clinic the nation's priority?
They have already been spending trillions in maintenance of the clinic every year. How many times do they want to build aso Rock clinic?

APC IS THE GREATEST YAHOO YAHOO BUSINESS.
