A
The pOH of a solution is the negative log of the concentration of OH ions. THis would be 9 in this case. The pOH is the opposite of pH. The scale is from 0 - 14. The lower the pOH, the more basic the solution is. pOH of 7 is neutral. Lower than 7 is basic and higher than 7 is acidic. If the pOH of a solution is 9, the pH of the solution is 5. The pOH and the pH should add up to be 14. I hope this helps.

you could desire to function some thing to each answer to make certain if some thing precipitates out. case in point, in case you upload NaCl to AgNO3, you will form a precipitate of AgCl. in case you upload NaCl to the NaNO3, no longer something happens. same is going for the copper combos.
