WebbIf pH >7, the solution is basic. The pOH should be looked in the perspective of OH-instead of H +. Whenever the value of pOH is less than 7, then it is considered basic. And therefore there are more OH-than H + in the solution. At pH 7, the substance or solution is at neutral and means that the concentration of H + and OH - ion is the same. WebbAs we have seen, [H +] and [OH −] values can be markedly different from one aqueous solution to another.So chemists defined a new scale that succinctly indicates the concentrations of either of these two ions. pH The negative logarithm of the hydrogen ion concentration. is a logarithmic function of [H +]:. pH = −log[H +]. pH is usually (but not …
