Base, in chemistry, anysubstance that in water solution is slippery tothe touch, tastes bitter, changes the colour of indicators (e.g., turns red litmus paper blue), reacts with acids to form salts, and promotes certain chemical reactions (base catalysis). ...

This is a logarithmic equation with a base 10. On this scale, a substance with a ph of 3 is ten times more acidic than a substance with a pH of 4, and 100 times more acidic than a substance with a pH of 5. Similarly, a substance with a pH of 9 is ten times more alkaline tha...
