Question

During the electrolysis of molten alumine 13.5 g Al are deposite in one hour . What is charge in faraday passed? (A) 3F ( b) 2F ( c) 1.5F (d) 1.0F

Answer 1

Answer:

Explanation:H2SO4 → 2H+ + SO42-

Note the production of positively charged hydrogen ions and also the reaction arrow, which only points to the right. All of the reactant (acid) is ionized into product.

Weak Acids

Weak acids do not completely dissociate into their ions in water. For example, HF dissociates into the H+ and F- ions in water, but some HF remains in solution, so it is not a strong acid. There are many more weak acids than strong acids. Most organic acids are weak acids. Here is a partial list, ordered from strongest to weakest.

HO2C2O2H - oxalic acid

H2SO3 - sulfurous acid

HSO4 - - hydrogen sulfate ion
