# Calculate the [H+] of each of the following solutions at 25°C. Identity each solution as neutral, acidic, or basic.a. [OH−] = 1.5 Mb. [OH−] = 3.6 × 10−15 Mc. [OH−] = 1.0 × 10−7 Md. [OH−] = 7.3 × 10−4 M

(a)

Interpretation Introduction

Interpretation: The [H+] of each of the given solutions is to be calculated. The solutions are to be identified as neutral, acidic or basic.

Concept introduction: A neutral species has a pH value equal to 7 , that is the [OH] is equal to the [H+] . An acidic species has a pH value less than 7 , that is the [OH] is less than the [H+] . A basic species has a pH value greater than 7 , that is the [H+] is less than the [OH] .

The equilibrium constant for water is denoted by Kw and is expressed as,

Kw=[H+][OH]

At 25°C , [H+][OH]=1×1014

Explanation

Explanation

To determine: The [H+] of each the given solution and its classification into neutral, acidic or a basic solution.

Given

[OH]=1.5M

The temperature is 25°C .

The [H+] is calculated by the formula,

Kw=[H+][OH]=1×1014

Substitute the given value of [OH] in the above expression.
