Hydrometer Temperature 19.5
Unknown A
Trial 1: 1.030 (g/m²)
Trial 2: 1.031 (g/m3)
Tial 3: 1.032 (g/m3)
What’s the average?

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.

thats how its supposed to be
