QUESTION:

Problem 68P

Classify each solution as acidic, basic, or neutral according to its pH value.

(c) pH = 13.0

(d) pH = 0.85

ANSWER:

Problem 68P

Classify each solution as acidic, basic, or neutral according to its pH value.

(a) pH = 4.0

(b) pH = 3.5

(c) pH = 13.0

(d) pH = 0.85

                                            Step by Step Solution

Step 1 of 4

*  If a solution has pH 1 to 7 , then hydronium ion concentration dominates the hydroxide ion concentration, so the solution will be acidic in nature.

*  If the value of pH is 7, then hydronium ion concentration equals the hydroxide ion concentration, so the solution will be neutral.

*  If the value of pH is 7 to 14 , then hydroxide ion concentration dominates the hydronium ion  concentration, so the solution will be basic.

(a)

The given value - pH = 4.0

The given pH value is less than 7, hence the solution is acidic.
