3) in peaches, [oh]=3.16x10-11 m a) find [h+ ] b) what is the ph? c) is the solution acidic, basic, or neutral?

a) [H⁺] = 3.16 x 10⁻⁴ M.

b) pH = 3.5.

c) The solution is acidic.

Explanation:

a) Find [H⁺]

∵ [H⁺] [OH⁻] = 10⁻¹⁴.

∴ [H⁺] = 10⁻¹⁴/ [OH⁻] = 10⁻¹⁴/ (3.16 x 10⁻¹¹ M) = 3.16 x 10⁻⁴ M.

b) What is the pH?

∵ pH = - log[H⁺].

[H⁺] = 3.16 x 10⁻⁴ M.

∴ pH = - log(3.16 x 10⁻⁴ M) = 3.5.

c) Is the solution acidic, basic, or neutral?

pH is a scale from 0 to 14.

∵ pH = 3.5 < 7.

∴ The solution is acidic.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
