What is the pH of a solution of 1.4 M HF in 1.9 M CaF2? (Ka HE = 7.2 x 10-4) IMPORTANT: When entering your answer: • Enter the number only (no units) • Do not leave any spaces • Include the sign if your answer is negative (not necessary for positive values) • Use a leading zero before the decimal when necessary Report your number to 2 decimal places (regardless of the significant figures) Correctly round your answer to the 2nd decimal place (margin of allowed error is only + 0.01, so always use un-rounded numbers in your calculations). If the last digits are zeros they will not display once you click away, but the answer will still be marked correct. Examples: 12.34 or -0.56
