In the first hand it means it is a fairly strong acid.
In a more accurate meaning, the pH is calculated as:
-log10 [H3O+]
Where [H3O+] means the concentration of hydroxide-ions in the water.
So, we know this:
-log10 [H3O+] = 2.00
So, it is not hard to calculate that the concentration of hydroxide ions is 0,01 g mol-1 .

What happens to pepsin at pH of 8?
It denatures (enzyme breaks down) because pepsin is best operational in a pH of around 2 or 3 in the stomach juices.
What happens to the buffer a pH capacity?
The buffer maintain the pH constant.
If a base is added to an acidic solution what happens to the ph?
Adding base will increase pH-level
What happens to the pH of distilled water when you add NaOH?
HCl : makes it acidic. it decreases the pH NaOH : makes it alkaline. it increases the pH
What happens to protein charge if pH value becomes lower than pi in 2 dimensional gel electrophoresis?
Its a acidic amino acid
What happens to a PH solution when it is neutralised?
The pH become 7,00.
What happens to pepsin at pH of 8?
It denatures (enzyme breaks down) because pepsin is best operational in a pH of around 2 or 3 in the stomach juices.
What happens to the pH in the beaker as the acid is added?
The pH drops. The stronger the acid the lower the pH.
What happens when the pH falls below its level?
The pH tends to be acidic.
What happens to the pH of a solution when its neutralised?
A neutralized solution has a pH of 7.
What happens to the buffer a pH capacity?
The buffer maintain the pH constant.
What happens after dipping a substance into a pH solution?
The color of the pH solution can be changed.
What happens when a strong acid mixes with a weak base?
A strong acid (1 or 2 pH) A weak base ( 8 or 9 pH) The mixture would still be acidic but not as much.
Which change shows a tenfold increases in concentration of h ions?
pH 2 -> pH 1
What happens to the pH level of the blood when exercising?
The pH level of the blood drops when exercising.
What happens to the pH of an alkali as it is neutralised?
The pH goes down to 7 as it is the neutral substance
Is a pH of 2 alkaline?
A pH of 2 is acid
