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. WebbThe pH scale is logarithmic and as a result, each whole pH value below 7 is ten times more acidic than the next higher value. For example, pH 4 is ten times more acidic than pH 5 and 100 times (10 times 10) more acidic than pH 6.

Bases you can find around the house include things like bleach and baking soda. According to the chart above (in blue), bleach has a pH of 13, while baking soda has a pH of 9.5. This means that bleach is more basic than baking soda. Higher pH values mean that something is more basic.

pH is defined as the decimal logarithm of the reciprocal of the hydrogen ion activity, aH+, in a solution. 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… WebbpH Level of Water The standard limit for the pH level of drinking water is 6.5–8.5.
