Please can you do a video for waec chemistry practical alternative B please.
Great teaching sir
Thanks and welcome
A MIXTURE OF THE TWO SOLUBLE GIVES ONE SOLUBLE NANO3 AND ONE INSOLUBLE PbCO3
U are good...just started following u recently...am a chemistry teacher too and u are articulate with ur teaching 👍
thanks for the compliments i really do appreciate
Sir why not add HNO3 before adding NaOH indrops and inexcess
they can decide to add anyone
yes its possible they can ask you to add anyone first
sir al is gelatinious ohcheck new school chemgreat vid
white ppt or gelatinous is not what will give the students mrk the main purpose is to identify weather there is a ppt of solution.so e nor matter
@@OkotoazaLeonard-ug5gr so why didnt you add calcium ion for naoh??cos it give white ppt as u sayAl and ca give white gel. ppt with naoh
Weldone. But the two salts are soluble. When you add water, you see a white ppt. When you filter you see white residue and colourless filtrate. The salts are soluble. But you say C is a mixture of soluble and insoluble salt. What do you think!
a mixture of the two soluble salt labelled as c gives a mixture of one soluble (nano3 and one insoluble pbco3
