PLEASE HELP M. THANK YOU IN ADVANCE♥️ Determining the State of Water
Using the phase diagram for water determine the state of water at the
following temperatures and pressures:
A. Solid B. Liquid C. Gas

(1.) -10°C and 50 kPa
(2.) 25 °C and 90 kPa
(3.) 50 °C and 40 kPa
(4.) 8O C and 5 kPa
(5.) -10 °C and 0.3 kPa
(6.) 50 °C and 0.3 kPa​

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.
