How do I determine the concentration of 2 separate acids in a solution of water if I know the overall pH of the solution?There exists both formic acid and acetic acid in a 1 liter solution of water. The overall solution pH is stated as 4.0 and it is also assumed that the 2 acids contribute equally to the pH. How do I then determine the molar concentration and quantity of each acid in the 1 liter solution of water?
A 6.11 g sample of Cu---Zn alloy reacts with excess aqueous HCl producing 1.26 L of H2(g) at 22.0 degrees C and 728 torr. Since only the Zn portion of the alloy reacts, calculate the percent Cu in the alloy.
