Use 0.50L of the buffer made from 2.5M citric acid and 0.5M sodium citrate to answer the following: The Ka of citric acid is 8.4 x 10-4 How many moles of acid are present in the buffer? [ Select ] ["0.25 mol", "3.0 mol", "0.20 mol", "1.25 mol"] How many moles of base are present in the buffer? [ Select ] ["0.25 mol", "0.20 mol", "3.0 mol", "1.25 mol"] What is the total volume of the solution if 0.025L of NaOH is added to the buffer? [ Select ] ["0.025 L", "0.50 L", "0.013 L", "0.525L"] How many moles of OH- are present in 0.025L of 3.0M NaOH? [ Select ] ["0.075 mol", "6.0 mol", "0.008 mol", "3.025 mol"] Calculate the pH if 0.025L of 3.0M NaOH is added to the buffer. [ Select ] ["pH = 0.28", "pH = 7.57", "pH = 2.52", "pH = 2.24"]
Use 0.50L of the buffer made from 2.5M citric acid and 0.5M sodium citrate to answer the following:
The Ka of citric acid is 8.4 x 10-4
