Tap water seldom has a pH of 7 exactly at the standard temperature of 25 degrees Celsius. The pH value of tap water is a little left or right of pH 7 due to the reaction of water with mineral salts and gases dissolved in it, and this pH value is variable with temperature. The pH is more usually less than 7 due in part to CO2 dissolved in it forming carbonic acid. Regarding pH 5 for "neutral" soil, that's a strange one for me. But I guess it's just that at PH 5, the acidity is low enough to be harmless to plants and other living things. Do you recall a time when shampoos were advertised with the label, "Balanced at pH 5"? Evidently the sellers were trying to give their shampoos a "scientific" mystique. From this one may deduce that at pH 5 the shampoo was harmless to scalp and hair and skin etc.
