Question

In butter, [H3O+] =6.0x10-7 M, what is the pH? Is butter acidic, basic, or neutral?

Answer 1

Label each solution as acidic, basic, or neutral based only on the stated pH.

milk of magnesia, pH = 10.5

pure water, pH = 7

wine, pH = 3.0

Solution

With a pH greater than 7, milk of magnesia is basic. (Milk of magnesia is largely Mg(OH)2.)

Pure water, with a pH of 7, is neutral.

With a pH of less than 7, wine is acidic.
