Where m is mass of solute per 100 g of water, m₁ - mass of solute, calculated from equation (4), m₂ - total mass of solution.

If you want to calculate of mass of solute per 100 g of water (H₂O), you can use equation (5): Knowing the mass percentage concentration (wt%), you can easily calculate mass of solute (m₁) (equation (4)): If you know density (d ) and molarity (c ) of the solution and molar mass (M ) of solute, you can calculate mass percentage concentration by a given mathematical equation (2):Īlternatively, if you know density (d) and mass percentage concentration (wt% ) of the solution and molar mass (M) of solute, you can calculate molarity by a given mathematical equation (3): So, there is no effect for H + ion concentration when it is calculated from pH value in different temperatures.How to calculate concentration - other useful equations There are only 2 terms in pH equation, H ion concentration and pH value. If I know pH value of aqueous solution and when I calculate H + ion concentration from pH equation, is it correct for every temperature? When, we measure the pH value of acidic solution and calculate H + ion concentration, it indicates the overall H + concentration of solution. So, pH value is uniform throughout the solution.

So, there is only one H + ion concentration throughout the aqueous solution. If there are two or more acids in a aqueous solution, all of them give H + ions in different amounts. In the answer too, you can see H + ion concentration is much lower than acetic acid concentration.Īsk your chemistry questions and find the answersĬan I use this calculator for an acid mixture such as HCl and H 2SO 4?

Whether acetic acid concentration is given, we cannot get a direct and easy relationship between acetic acid concentrationĪnd H + ion concentration because acetic acid is a weak acid. What is the H + concentration of acetic acid solution?īecause pH value is given, we can find the H + concentration directly from pH equation. We can substitute pH = 1 in pH equation.įrom pOH equation, OH - concentration can be calculated.Īqueous acetic acid solution has the pH value of 3 and concentration of acetic acid is 0.05 mol dm -3. What are the H + and OH - concentrations in pH = 13 solution?īecause pH = 13, this solution is a strong basic solution. What is the H + concentration in an aqueous solution which show pH = 1 ?īecause pH = 1, this solution is a strong acidic solution. Example problems for calculating H + concentration when pH or pOH values are known
