ive spent over 2 hours on this question and i am unable to solve it. If anyone could help it would be greatly appreciated.
What is the pH of the solution that results from mixing the following four solutions together?
(1) 150. mL of 0.250 M NaCl
(2) 300. mL of 0.200 M HCl
(3) 100. mL of 0.050 M HNO3
(4) 450. mL of 0.200 M NaOAc
HCl and HNO3 are both strong acids and give 0.065 mol of h3o.
There are also 0.09 mol of NaOAc which is a weak base in the solution.
The hydronium reacts with NaOAc, resulting in 0.025 mol of NaOAc in a 1L solution
i do not know what to do after, I've reacted so many possible combinations and still cannot get an answer. The possiable answers are as follows:
a. ) 4.22
b. ) 4.33
c. ) 4.74
d. ) 4.98
e. ) 5.16
