Hello.
00:01
So in this question we have to find out the reason for not doing the titration of alkali salts.
00:20
Of alkali salts of such acids like citrate tartaric acid is there with the same manner as the carbonates are titrated.
00:29
So, see, both are of equal strength, are of equal.
00:37
Strength there and then the equivalent ph will be neutral in this case.
00:47
But however, weak acids are not often, these are not often used for titrated or titration against the weak basis.
01:03
Means weak acid they are of a not titrated against weak basis because the color change is shown with this indicator it is very quick or we can say that there is a quick change in a color and for the observer it is very difficult to observe or to see the change of the color so that is why the alkali salts of such acids as citric or tartaric be titrated directly with the strong acid, not with the weak basis.
01:50
They will titrated with strong acid directly in the same manner as the soluble carbonates are titrated.
02:06
And also the salts of citric and tartaric acid, they are barely soluble.
02:12
Water and therefore the direct titration it is not possible as only a small amount of the salts it is solubilized in that case so now for the next one we have to give the example the neutralization in the case of in the field of medicine see we sometimes human beings suffers from acidity or we can say gastric problems and it arise due to the due to an increase of an acid in the stomach in stomach.
02:55
So ant acids or ant acids, these are the medicines containing bases like sodium bicarbonate or magnesium hydroxide, they neutralize the excess of acid in the stomach...
