62. Solving a chemistry problem

1. To determine sulfuric acid in the analyzed solution, a galvanic cell was used, consisting of an indicator hydrogen electrode and a saturated silver chloride reference electrode at 25 0C:
Pt(H2) | H2SO4 || KS1nas, | AgCl, Ag
The measured EMF value turned out to be 0.396 V. Calculate the pH of the analyzed solution, the molar concentration of the acid in it, and the mass of H2SO4 in 250 ml of the solution. Describe the device and properties of the hydrogen electrode.
