Chemist Johannes Bronsted and scientist Thomas Lowry proposed that an acid should be defined as a substance that can donate a proton, while a base is any substance that can accept protons. American chemist G.N. Lewis proposed a different theory. Learn about three popular scientific definitions of...

Serotonin stimulates acid–base transport by the anterior stomach region of the midgut in vitro. The function of this stimulation is assumed to be maintenance of optimal conditions for digestion and absorption of nutrients rather than regulation of hemolymph acid–base homeostasis. ...
Molecular weight = gm s /mole Normality: Number of gram equivalent of solute dissolved in 1 litre of solution It is based on chemical reaction Normality represents the molar concentration ‘(H+ for Acid)’ or ‘ (OH- for base)’ Questions: 2. Why the color of indicator changes?
