Chapter 10: Q.10.9 (page 359)

Identify each of the solutions in problem 10.88 as acidic, basic, or neutral.

Short Answer

Expert verified

a. Neutral

b. acidic

c. acidic

d. acidic

Step by step solution

01

Given Information

Acidic solutions are estimated to have lower pH values than basic or alkaline solutions. pH or "potential of hydrogen" is a scale used to specify the acidity or basicity of a fluid solution.

a.OH鈭�=1.0脳10鈭�7Mb.H3O+=4.2脳10鈭�3Mc.H3O+=0.0001Md.OH鈭�=8.5脳10鈭�9M

02

Explanation

A solution is acidic if its pH is less than 7. A solution is basic if its pH is greater than 7. A solution is neutral if its pH is equal to 7.

Hence, applying the above logic the solutions are -

a.OH鈭�=1.0脳10鈭�7Mis Neutral

b.H3O+=4.2脳10鈭�3Mis acidic

c.H3O+=0.0001Mis acidic

d.OH鈭�=8.5脳10鈭�9Mis acidic
