The amount (in milliliters) of the strong monoprotic acid solution with pH=4.12 that is needed to change the 528 mL of the same acid solution at pH=5.76 to pH=5.34 has to be calaculated
The concentration of hydrogen ion is measured using scale. The acidity of aqueous solution is expressed by scale.
The of a solution is defined as the negative base-10 logarithm of the hydrogen or hydronium ion concentration.
On rearranging, the concentration of hydrogen ion can be calculated using pH as follows,
