Textbook Problem

Match the following pH values: 1, 2, 5, 6, 6.5, 8, 11, 11, and 13 with the following chemicals (of equal concentration): HBr, NaOH, NaF, NaCN, NH4F. CH3NH3F, HF. HCN. and NH3. Answer this question without performing calculations.

Interpretation Introduction

Interpretation: The given pH values and chemicals are to be matched correctly without performing any calculations.

Concept introduction: An acid that dissociates into hydrogen ions completely is known as strong acid whereas an acid that dissociates partially into hydrogen ions is known as weak acid.

The pH value of strong acid is very low whereas the pH value of weak acid is very high.

Explanation

Explanation

To determine: The correct match of each value of given pH and chemicals.

The order of given pH is,

HF-1,HBr-2,HCN-5,CH3NH3-6,NH4F-8,NaF-8,NaCN-11,NH3-11,NaOH-13

The scale of acidity from 0 to 14 is known as pH scale. The value of pH less than seven corresponds to acids whereas the value of pH greater than seven corresponds to base.

The pH value of strong acid is close to 1 whereas the pH value of strong base is close to 14 .

If a compound contains H+ ion, then it is an acid whereas if a compound contain OH ion, then it is a base.

Methyl groups (CH3) are weak acid.

Refer to table 13-7 .

The acidic strength of compound depends on their bond strength.

The order of acidic strength is HF>HBr>HCN
