indicators are substances that change their color when they come in contact with acids or bases......ex. litmus paper
ph scale is an universal indicator...it states it nature(acidic/basic/neutral) and also shows its strength . it changes color accordingly ......
some crystals,probably salt will have some water inside them ......this is the water of crystallization
