The pH of a solution is the negative logarithm of the molar concentration of hydronium ion, that is, pH = -log[H₂O¹] In neutral solutions at 25°C. [H₂O-107 M and pH-7 As H₂O increases, pH decreases, so acidic solutions have a pH of less than 7. Basic solutions have a pH greater than 7. The hydroxide and hydronium ion concentrations are related by the the lon-product constant of water, K as follows: K-1.0 x 10H₂OOH in the same way as the pH, we can define the POH as pOH = -log(OH) follows from the K expression that pH +pOH = 14. Correct According to the mathematical properties of logarithms, the only digits that are significant figures in logarithms are those to the right of the decimal point. The given concentration has two significant figures: therefore the pH should have two digits after the decimal point. Part C The other way to solve this problem would be to calculate the pOH and then subtract it from 14 to get the pH value. Previous Answers pH = Calculate the pH of a 0.10 Af solution of hydrazine.
