Chemists also express an amount of substance in terms of the number of moles (as well as the mass, or weight, in g). So concentrations in solution can be expressed as number of mol per L. This is called the molarity of the solution and is given the symbol M.

Molarity = moles of solute /Liters of solution % by mass = grams of solute /grams of solution x 100 % by volume =volume of solute/ volume of solution x 100 ppm = grams of solute/ grams of solution x 1,000,000. Ex1: What is the molarity of a solution that contains 4.0mol of NaOH in 0.50L of solution? Molarity = moles of solute /Liters of solution

(i) measures PPM of Hydrogen Ion (ii) logarithmic function of [H+] Logs are functions of exponents… for example…the log of 1000, which is 103 = the log of 0.01, which 10-2 = b. Equation c. Examples, Given [H+] find pH (in your calculator: - key, log key, number value, enter key) If [H+] = 9.5 X 10-10, what is pH? Is this an acid or base?

Ca and Mg stock solutions, 1000 ppm. Prepare 100 mL of a solution containing both Ca and Mg at 100 ppm. Working standards: Line up and label five 100 mL volumetrics. To each add 10 mL of the La solution and 2 mL of the 6 M HCl. Then add appropriate amounts of the mixed 100 ppm standard to make standards with 0, 1.0, 2.0, 5.0, and 10.0 ppm.

1. You will need to prepare a data sheet for this week’s experiment. It will need one set of spaces to list the name, type, appearance, and nominal concentration of the vinegar you choose and the molarity of the sodium hydroxide. You also need to provide spaces for up to 4 sets of titration data – 4 trials.
