Question

Find the hydrogen ion and hydroxide ion concentration in 0.02M solution of tetraoxosulphate(vi) acid.

Answer 1

Answer: 0.04M

Step-by-step explanation:

Tetraoxosulphate(VI) acid has a formula of H2SO4.

The concentration of the whole acid is 0.02M, and there are 2 hydrogens in the formula. That means we multiply 0.02M * 2, giving the answer of 0.04M.

Another visual explanation...

H2SO4 = H2(2+) + SO4(2-)

There are two hydrogens, the double amount of concentration of H2SO4, giving the answer of 0.04M.
