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). ...
Titrations are conducted in many laboratories as a quantitative method used to calculate the concentration of an acid or base via a neutralization reaction. An acid or base is used as the titrant that has a known concentration. It is slowly added to the unknown acid or base until n...
