3) a 10.00-ml sample of 0.1000 m kh2po4 was titrated with 0.1000 m hcl ka for phosphoric acid (h3po4): ka1= 7.50x10-3 ; ka2=6.20x10-8 ; ka3= 4.20x10-10 calculate the ph after addition of 10.00 ml of hcl to the kh2po4 solution?

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.

answer: they produce more slow than unicellular organisms.
