Naoh effect on ph

Witryna9 wrz 2024 · The pH of a buffer solution may be calculated as follows: p H = p K a + l o g n A n H A Where pK a = dissociation constant of the acid, nA = initial number of moles of salt in the buffer, and nHA = initial number of moles of acid in the buffer. Witryna30 gru 2024 · Why NaOH is a strong base? When strong acid and strong base reacts they tend to form the solution having a pH value equal to 7 i.e. the solution doesn’t have both acidic and alkaline properties. Therefore, a solution of sodium chloride holds neither acidic properties nor alkaline properties.
