Natural rainwater has a pH of about 5.6 because some atmospheric CO2 dissolves in it to form the weak acid H2CO3 (carbonic acid); but both sulfuric and nitric acids are strong acids and their impact on the pH of rainwater is far greater for a given molar quantity dissolved than is that...
ranges from 0-14. Litmus paper is an indicator used to tell if a substance is an acid or a base. The colour of the paper matches up with the numbers on the pH scale to indicate what kind of substance is being tested. For example, Vinegar is an acid and measures 2.4 on the pH ...
[449]. When extreme acid pollution is mitigated, cladocerans are slow to reestablish populations[503], perhaps because some cladocerans require relative high calcium concentrations for proper exoskeleton development[510].Holopediumsubstitutes a muco-polysaccharide covering for a stiffcarapace, and so can...
