pH + pOH = 14 for all aqueous solutions

The pH of 1 $$\times$$ 10^-8 M HCl is 8

96,500 coulombs of electricity when passed through a CuSO₄ solution deposits 1 gram equivalent of copper at the cathode

The conjugate base of $$H_2PO_4^-$$ is $$HPO_4^{2-}$$

slightly higher than that when the thunderstorm is not there

uninfluenced by occurence of thunderstorm

which depends on the amount of dust in air

slightly lower than that of rain water without thunderstorm
