the answer is at wiki and the amswer is neutral
a pH of 7 is neutral. anything below 7 is acidic, and everything above is basic.
in neutral conditions there is no change in colour of litmus....
No, they are salty. That's why they sting a bit when they contact a break in the skin.
No. They function best at the pH corresponding to their usual/intended environment. For example, pepsin, present in the stomach, which is highly acidic, functions best at acidic pH, while trypsin, secreted into the duodenum together with basic bicarbonate, functions best at moderately basic pH. This is true also within subcellular compartments: the optimal pH of lysosomal enzymes is acidic, matching the acidic proteolytic environment inside the lysosome. That said, most enzymes present in the cytosol (~neutral) and blood (~neutral) function best around neutral pH.
Rain water is generally acidic

Urea is a neutral compound. It is neither acidic nor basic in aqueous solutions.
Tomato is acidic.

It is a neutral salt but its aqueous solution is acidic in nature.
Methyl is neither acidic nor basic. It is a neutral compound.
