The molar solubility (in ol L^-1) of a sparingly soluble salt MX₄ is "s". The corresponding solubility product is K_sp. 's' is given in term of K_sp by the relation :

s = (256 K_sp)^1/5

s = (128 K_sp)^1/4

s = ( K_sp / 128)^1/4

s = (K_sp / 256)^1/5

When rain is accompanied by a thunderstorm, the collected rain water will have a pH value :

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
