The titration was performed on a mixture of HCl and H3PO4 with 0.099M NaOH. You must show your work for full credit. What are the coordinates of the first and second equivalence points

neutrons are in the middle of the atom and the electrons, which are much smaller.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
