What would be the result of the reaction of the compound with HBr?
I just have no idea how to approach this.
A solution containing 0.125M of a weak base (pKb = 5.00) is to be titrated using 0.568M HClO4.Calculate the solution pH at 2.00% of Ve, and at 5.00mL past Ve.I calculated the equiv point to be 22.01mLs, but I do not know for sure how to finish. Can you explain steps for before and after e.p.??
Now consider the reverse reaction,Cu(NH3)42+ Cu2+ + 4NH3What is the equilibrium constant for this reaction? 10Begining with the "final" concentrations from the table above AND taking equilibrium into account this time, please complete the following reaction table.Cu(NH3)42+ Cu2+ + 4NH3initial 11M 12M 13M14M 15M 16Mequilibrium 17M 18M 19MWhat percentage of the original Cu2+ is still present as free Cu2+ after addition of the NH3? 20 %So, how good was the original assumption that all the Cu2+ would be present as Cu(NH3)42+?

How would each of the following affect the accuracy of the calculated neutralizing power of antacid (too high, too low, or no effect) a. The titration flask was wet with distilled water when the antacid was added. b. The buret was not rinsed with NaOH solution before titrating, and water was in the tip. c. The antacid was not cut in half exactly before weighing. d. The solution mixture of reacted antacid and excess HCl spattered out of the flask during boiling.
