what is an alkaline chemical
A pH of spot on 7 denotes a neutral solution (neither acidic or alkaline). Any pH below 7 is acidic, whilst any pH above 7 is termed alkaline. Water molecules have the chemical formula H2O. However, these molecules are capable of splitting up slightly in solution, in H+ and OHâ (hydroxide) ions. In a neutral solution, the concentrations of these two ions are equal.
