A 5.00 sample of a dry mixture of potassium hydroxide, potassium carbonate as well as potassium chloride is reacted with 0.100L of 2.00M HCL solution.
a) A 249ml sample of dry carbon dioxide gas, measured at 22 C and 740 torr, is obtained from this reaction. Explain what is the percentage of potassium carbonate in this mixture?
b) The excess HCL is found by titration to be chemically equivalent to 86.6ml of 1.50M NaOH. Compute the percentages of potassium hydroxide and potassium chloride in the original mixture.
