(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Calculate pH of the 1,96% solution of H3PO4 (ρ≈1 g/cm^3). Take in account only the first constant of dissociation (7,5 * 10^-3 mol/cubic dm). The reduction of the concentration of H3PO4 because of dissociation can be ignored.

% = 1,96%

ρ (H3PO4) ≈1 g/cm^3

K = 7,5 * 10^-3 mol/cubic dm

2. Relevant equations

No equations in this task.

3. The attempt at a solution

Couldn't even attempt to solve it, because I don't know how to put the information together.
