Maleic acid is a diprotic acid with ionization constants a1=1.20×10−2 and a2=5.37×10−7 . Calculate the pH of a 0.296 M potassium hydrogen maleate ( KHM ) solution.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
