![]() ![]() ![]() The reason for the difference is that teachers like to change the values slightly so as to not allow a student to simply look up the correct answer and claim they did all their work on the calculator. Note: the book value for the K sp of Mg(OH) 2 is 5.61 x 10¯ 12. Video is conducted kn both Sinhala & English. = 1.479 x 10¯ 4 M divided by 2 = 7.395 x 10¯ 5 MĦ) We now have the necessary values to put into the K sp expression: 42 Dislike Share Chem Talk 829 subscribers Ksp Chemistry This video explains how to do basic Ksp calculations. = 10¯ pOH = 10¯ 3.83 = 1.479 x 10¯ 4 Mĥ) From the chemical equation, we note that the is half the value of the, therefore: If you were to see a problem where the specified temperature was different, it's probably just that the reference source gave a K sp that, for whatever reason, was not at 25.0 ☌.Įxample #1: A saturated solution of Mg(OH) 2 is prepared. All problems in this tutorial are taken to be at 25.0 ☌. Then, we will use the K sp expression to calculate the K spįinal Note: K sp are almost always given at 25.0 ☌ in reference sources. To do this, we will use the pH and acid base concepts. To solve the problem, we must first calculate the. If you lack one or the other of these skills, just be aware you just might struggle a little in your understanding of this problem type. Warning: you need to know about K sp AND acid base ideas to do this problem type. We know the pH and we know the solution is saturated. Please be aware that this problem does not require a concentration to be given in the problem. Return to a listing of many types of acid base problems and their solutions Calculate the K sp of a Saturated Solution When Given the pH ![]()
