Question- A student is presented with a 0.110 M solution of an unknown weak acid. The student measures the pH of that solution and determines a value of 3.25 for the unknown solution. What then, is the Ka of this weak acid? What is the pKa?
I am in hurry anyone is there provide me the answer in quick phase
We are given an unknown antacid pill and through the procedure in this lab we determine its cost effectiveness to be 5.0x10-1 mole of acid/$. Can we also determine the number of moles of base in the pill
