The question asks to find the [OH], [Ph], and [OH] concentration with the given information that is 1.50M of [H30+]. You can get ph 0.176 and OH from that as 14.17. However, how would you get the OH concentration? I thought you would use the equation that is [M]= 10^-pOH. However, you get an incorrect number. Why would you not use the negative pOH?
The textbook says it would be 1.5x10^-14Ryan Chang 3A wrote:You are using the correct formula to find the concentration of OH, which is [M]=10^-POH. Plugging in the numbers you get: 10^-14.176 = 6.668 x 10^-15 M, which is the correct answer.
