0.015924 grams of CaO should be dissolved in sufficient water to make 1.00 L of a solution with pH of 10.50
The pH scale determines how acidic or basic water is. The range is 0 to 14, with 7 representing neutrality. Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
The pH is 10.6, the pH is 14, and the pH is 3.4.
Thus, the issue. of OH- is 10 (-3.4) This represents the quantity of CaO needed in a 1L solution. Once you have the moles, you can calculate the solution by multiplying it by the molar mass of CaO (40 gm/mol).
The result of the computation is 0.015924 gms.
