Chapter 14, Problem 30CI

(a)

Interpretation Introduction

Interpretation : The molarity of HCl solution needs to be calculated.

Concept Introduction : The acid base reaction is also called as neutralization reaction. It is a reaction of acid and base that results the formation of salt and water. The acidic and basic nature of substances can be checked with the help of pH of solution. The pH can be calculated as follows:

  $\text{pH}=-\log \left[{\text{H}}^{+}\right]$

Here, $\left[{\text{H}}^{+}\right]$ is hydrogen ion concentration.

(b)

Interpretation Introduction

Interpretation : The concentration of hydronium ion and pH of the HCl solution needs to be calculated.

Concept Introduction : The acid base reaction is also called as neutralization reaction. It is a reaction of acid and base that results the formation of salt and water. The acidic and basic nature of substances can be checked with the help of pH of solution. The pH can be calculated as follows:

  $\text{pH}=-\log \left[{\text{H}}^{+}\right]$

Here, $\left[{\text{H}}^{+}\right]$ is hydrogen ion concentration.

(c)

Interpretation Introduction

Interpretation : The balanced chemical reaction of HCl and ${\text{MgCO}}_{\text{3}}$ needs to be determined.

Concept Introduction : A chemical equation is said to be balanced if the number of atoms of same element are equal in both sides of the reaction arrow.

(d)

Interpretation Introduction

Interpretation : The volume of HCl solution needed to react with 350 mg of ${\text{MgCO}}_{\text{3}}$ needs to be determined.

Concept Introduction : The molarity of the solution is defined as number of moles of solute in 1 L of the solution. It is mathematically represented as follows:

  $M=\frac{n}{V\left(L\right)}$

Here, n is number of moles, V is volume of solution in L.
