This question has multiple parts. Work all the parts to get the most points. For each of the following cases, decide whether the pH is less than 7, equal to 7, or greater than 7 0 45 mL of 0.40 M H3 PO4 is mixed with 45 mL of 0.80 M NaOH . The pH of the solution is less than 7. The pil of the solution is equal to 7 The pH of the solution is greater than 7. b30. mL of 0.60 M HCN is mixed with 30. mL of 0.60 M NaOH. The pH of the solution is less than 7. The pH of the solution is equal to 7. The pH of the solution is greater than 7. 65 mL of 0.30 M HCI04 is mixed with 65 mL of 0.30 M NaOH The pH of the solution is less than 7. The pH of the solution is equal to 7 The pH of the solution is greater than 7. Submit Answer Try Another Version 2 item attempts remaining

Explanation / Answer

A.

pH > 7.0 Becasue base is strong but acid weak so, it results basic solution

B.

pH > 7.0 Becasue base is strong but acid weak so, it results basic solution
