How about these questions are these right? What is the correct conjugate base for H3PO4? PO4-3 H2PO4- Phosphate HPO4-2 Cl- I chose number 2 what formula defines pH? log(H+) log(OH-) -log(H+) -log(OH-) none of the above I chose 3 What ion is produced in basic or alkaline solutions? hydroxide OH- Hydrogen both a&b are correct none of the above I chose 4 If a solution has a pH of 3.5, which statement is true? the solution is acidic the solution is basic the solution has excess hydroxide ions both b&c are correct you could never drink a solution with a pH of 3.5 I chose 1

I came up with 4.43 log(3.7*10-5)=4.43

I have too questions that I am having a problem with and I am wondering if someone could help me. What ion is in excess in acidic acid solutions? Cl- H3O+ OH- Hydroxide hydrogen gas A buffer functions to maintain a pH of 7.0 maintain a neutral pH maintain a fairly constant pH decrease chances for survival dilutes bases The answers that I chose was b for the first question and c for the second one. Oh, one more thing I am having a problem writing a pH for a solution with a hydrogen ion concentrating of 3.7 x 10-5
