WebbThis means that this acid has a higher CONCENTRATION of H+ molecules. This concentration is written as [H+] and because it is directly related to pH, it can be used to calculate pH, which you will see later. ... If a substance is 7 on the pH scale, it is neutral, meaning it is neither an acid nor a base (water, for example, is neutral).

WebbpH is a representation of hydrogen ion activity in a liquid. It is the negative logarithm of the number of hydrogen ions (in moles) per liter of liquid. Thus: 10 -11 moles of hydrogen ions in 1 liter of liquid = 11 pH. 10 -5.3 moles of hydrogen ions in 1 liter of liquid = 5.3 pH. Webbför 2 dagar sedan · (piː eɪtʃ ) uncountable noun [oft a NOUN] The pH of a solution indicates how acid or alkaline the solution is.

For example, for a solution with a hydrogen ion activity of 5×10 (at that level, this is essentially the number of moles of hydrogen ions per litre of solution) the argument of the logarithm is 1/(5×10 ) = 2×10 ; thus such a solution has a pH o…
WebbH 2 SO 4 is a dibasic acid. Sulfuric acid can give two H + ions. That means, one sulfuric acid molecule can reacts with two hydroxyl ions. H 2 SO 4 → 2H + + SO 4 2-. H + ions can be expressed as H 3 O + ions.. According to the stoichiometry, concentration of H + ions is twice as H 2 SO 4 concentration. [H +] = 2 * [H 2 SO 4] .
