Sections 11.4-11.6 t Problem 11.42 with feedback Clinical Application Calculate the OH of each aqueous solution with the following [H0]. You may want to reference (Pages 413-415) Section 11.5 while completing this problem. -Part A baking soda, 2.0 x 10 M Express the molarity to two significant figures Request Answer Part B blood, 4.5 x 10M Express the molarity to two significant figures -Part C milk, 5.0 × 10-7 M Express the molarity to two significant figures Part D pancreatic juice, 4.1 x 10M Express the molarity to two significant figures. ??? ??

Explanation / Answer

[H3O+] [OH-] = 1.0 x 10-14 M

[OH-] = 1.0 x 10-14 / [H3O+]

A) [OH-] = 1.0 x 10-14 / 2.0 x 10-8

[OH-] = 5.0 x 10-7 M

B) [OH-] = 1.0 x 10-14 / 4.5 x 10-8

[OH-] = 2.2 x 10-7 M

C) [OH-] = 1.0 x 10-14 / 5.0 x 10-7

[OH-] = 2.0 x 10-8 M

D) [OH-] = 1.0 x 10-14 / 4.1 x 10-9

[OH-] = 2.4 x 10-6 M
