Question

Give reasons why: a) tartaric acid is added while making baking powder? b) bleaching powder is used fr disinfecting water c) Strong acid and concentrated acid does not mean the same thing? ....plse answer

Answer 1

@ to remeove and neutralise the effect of base na2co3

Answer 2

A)Tartaric acid is a weak and mild acid. It is mixed with baking soda to prepare baking powder. When baking powder is used in batters, the tartaric acid reacts with baking soda and neutralises the bitter taste without affecting its ability to produce CO2 and H2O

B)Addition of bleaching powder to water called chlorination and is a part of drinking water treatment process due to its important disinfectant properties. Bleaching powder contains sodium hypochlorite, when applied to water, each of these forms “free chlorine,” which destroys pathogenic (disease-causing) organisms.

C)In common (street) parlance, those may in fact have the same meaning, but not in technical (scientific) parlance. A strong acid is one that fully dissociates in water. Nitric acid (whether concentrated or dilute) is a strong acid. Acetic acid is a weak acid, even if it is highly concentrated.
