Chapter 10: Q.10.89 (page 359)

Identify each of the solutions in problem 10.87 as acidic, basic, or neutral.

Short Answer

Expert verified

a.Neutral

b.acidic

c.acidic

d.acidic

Step by step solution

01

Given Information

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

$a. [H_{3} O^{+}] = 1.0 \times 10^{- 11} M b . [H_{3} O^{+}] = 5.0 \times 10^{- 2} M c . [{OH}^{-}] = 3.5 \times 10^{- 4} M d . [{OH}^{-}] = 0.005 M$

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, the solutions are -

a. $[H_{3} O^{+}] = 1.0 \times 10^{- 11} M$ is Neutral

b. $[H_{3} O^{+}] = 5.0 \times 10^{- 2} M$ is acidic

c. $[{OH}^{-}] = 3.5 \times 10^{- 4} M$ is acidic

d. $[{OH}^{-}] = 0.005 M$ is acidic

Most popular questions from this chapter

Write the balanced chemical equation for the neutralization reaction of stomach acid HCL with Al(OH)3, an ingredient in some antacids.

State whether each of the following is acidic, basic, or neutral:

a. soda $p H 13.22$

b. shampoo, $p H 5.7$

c. laundry detergent, $p H 9.44$

d. rain $p H 5.8$

e. honey, $p H 3.9$

f. cheese, $pH 4.9$

Complete the following table-

How many grams of $C a C O_{3}$ are required to neutralize 100mL of stomach acid, which is equivalent to 0.0400 M HCL?

In an acidic solution, how does the concentration of $H_{3} O^{+}$ compare to the concentration of ${OH}^{-}$ ?
