2024 CHEMISTRY WAEC PRACTICAL | REDOX TITRATION | SALT ANALYSIS FOR BOTH TEACHERS AND STUDENTS 

Thanks so much 😊🎉, I'm humbled

Thanks so much

Thanks so much my Dear

You are his students nii

@@SaMoraq Yes ☑️

My Boss 🎉

Thanks so much dear

I finally used hydrated FeSO4 because the anhydrous I had was too small, and I tried buying from the market but it was scarce, so I quickly converted the 5.5g of the supposed anhydrous into 10.06g for hydrated, It gave me my exact tire around 18.30 above

Watch my recent video to learn how to do that

Anhydrous fe2 is virtually not available in my area. I was able to manipulate the hydrated and got 19.00cm

@@rahmahomale5351 I'm happy 😊

Thanks so much my fellow colleague

The Lead nitrate would convert to lead carbonate(Residue) when the residue PbCO3 is heated, it will produce PbO(yellow when cold) and brownish/Red when hot then it will give off CO2 gas

@@Basilhenry185 Thank you. However my question is on the original mixture of sodium carbonate and lead nitrate (Cn). Lead carbonate is formed when water is added to the salts mixture and subsequent double decomposition reaction occurs. Simple put, what will happen if we heat the mixture of sodium carbonate and lead nitrate without adding water?

@@lizharrison808 we can't be asked what because they already asked us to mix the salts in 1:1 proportion

You're highly welcome 🎉

Thanks so much dear

Your value is supposed to be around 17-19cm3

Check my recent video so you understand how you can prepare the hydrated FeSO4 to give you an accurate value

For redox value is hardly go beyond 10.

@@mustaphaibrahim8793 yeah but if you calculate it theoretically, you would get around 17-19cm3, follow the instructions using anhydrous FeSO4, you will get it

Your Value is supposed to be around 16-19cm3

No prob. Sir i discovered y it's not same with urs I used H2C2O4 and 10cm3 H2SO4 According to d question.

This video is to enlighten students on how to stay within range of their values

Thanks so much, I'm gland we are able to deliver, all glory to God Almighty

Glad you enjoyed it!🎉

Thanks so much 🎉
