Question

Part F
If the [OH] in a solution is 8×105M, what is the [H3O+]?
Express your answer to one significant figure.

Part G
If the [OH] in a solution is 8×105M, what is the pH of the solution?
Express your answer using one decimal place.

Part H
If the [H3O+] in a solution is 1×102M, what is the [OH]?
Express your answer to one significant figure.

Part I
If the [H3O+] in a solution is 1×102M, what is the pH?
Express your answer using one decimal place.

Part J
If the pH of the solution is 13.0, what is the [H3O+]?
Express your answer to one significant figure.

Part K
If the pH of the solution is 13.0, what is the [OH]?
Express your answer to one significant figure.

PART(F)

[H3O+] = 10-14/[OH-]

= 10-14 / (8*10-5)

=1.25 * 10-10 M
PART(G)

pH = - log[H3O+]

pH = - Log(1.25*10-10)

pH = 9.89
PART(H)

[OH-] = 10-14/[H3O+]

= 10-14 / (1*10-2)

= 10-12 M
PART(I)

pH = - LOg[H3O+]

pH = -Log(1*10-2)

pH = 2
PART(J)

pH = - Log[H3O+]

[H3O+] = 10-pH

= 10-13
PART(K)

[OH-] = 10-14 / [H3O+]

= 10-14 / (10-13)

= 10-1 M
