Consider the solubility of calcium fluoride. The relevant equation is: CaF 2 (s) Ca 2+ (aq) + 2 F - (aq) The equilibrium constant expression is: K sp = [Ca 2+ ] [F - ] 2 This expression describes a solution at equilibrium where the rate of dissolving solid is equal to the ...
What is the molarity of a solution of NaOH if 23.4 mL are required to neutralize 25 mL of 0.25 M H2SO4? What is the molarity of a solution of NaOH if 29.4 mL is required to neutralize 25 mL of 0.25 M H_2SO_4? Determine...
Divide the mass of the solute by the molar mass to get the number of moles of solute. In this case, work out 200 ÷ 58 = 3.4483 moles of solute.Calculating Molarity When you know moles of solute, you can work out molarity (M), the concentration of a solution expressed as the number...
equilibrium of water. From the hydrogen ion molarity one can calculate a pH value, which is important in determining whether a given solution is more acidic or basic than pure water. The calculation can also be performed in reverse, by isolating the pH equation for the...
What must the molarity of benzoic acid (C6H5COOH) be to get a pH of 2.25 if the pKa is 4.20? Calculate the pH of a solution made by dissolving 16.5 g of potassium acetate in 150 mL of solution. (The Ka of acetic acid is 1.8 x 10-5.) ...
