Chemistry
Calculate the molar solubility of MgCO3 in a solution that already contains 1.7×10−3 M sodium carbonate. MgCO3 Ksp = 6.82 x 10-6 IMPORTANT NOTE: You must use the quadratic equation to solve this problem. (DrBob222- thank you so much for all your help!)
Chemistry
how did you get (that's 0.17M x 1/2 = 0.085M)
Chemistry
What is the ph at the equivalence point for a titration of 250 mL of 0.17M piperidine with 0.17 M nitric acid. (piperidine: Kb = 1.3 x 10-3)
Chemistry
Consider the titration of 41.2ml of 0.230 M HF with 0.220 M NaOH . Calculate the ph after the addition of 11.9ml of sodium hydroxide.(HF: Ka = 3.50 x 10-4) Please, I need step by step on on how to solve this type of problem. Thank you very much!
