WebApr 13, 2024 · pH = – log [H +] Note that [H +] means the concentration H + ions in mol dm -3. pH values don’t have units – just quote the numerical value. Because strong acids dissociate completely it is usually easy to calculate their pH. But weak acids don’t behave like that – their dissociation is an equilibrium that varies with temperature.

WebJun 26, 2024 · A weak acid only partially dissociates from its salt. The pH will rise normally at first, but as it reaches a zone where the solution seems to be buffered, the slope levels out. After this zone, the pH rises sharply through its equivalence point and levels out again like the strong acid/strong base reaction.

WebThe difference between the two is that muriatic acid is a strong acid and vinegar is a weak acid. Muriatic acid is strong because it is very good at transferring an H + ion to a water molecule. In a 6 M solution of hydrochloric acid, 99.996% of the HCl molecules react with water to form H 3 O + and Cl-ions. WebThe pH scale is often said to range from 0 to 14, and most solutions do fall within this range, although it’s possible to get a pH below 0 or above 14.
