Chapter 4, Problem 69E

Interpretation Introduction

Interpretation:

Whether the resulting solution is neutral or not should be determined. If not, the concentration of excess proton or hydroxide ions left in the solution should be calculated.

Concept Introduction:

Mole is SI unit which is used to measure the quantity of the substance. It is the quantity of a substance which contains same number of atoms as present in accurately 12.00 g of carbon-12 is known as mole.

Number of moles of a compound is defined as the ratio of given mass of the compound to the molar or molecular mass of the compound.

The mathematical expression is given by:

Number of moles = $\frac{\text{ mass of the compound}}{\text{molar mass of the compound}}$

Molarity is defined as the ratio of number of moles to the volume of solution in L.

The mathematical expression is:

  $\text{Molarity =}\frac{\text{number of moles}}{\text{volume of solution in L}}$

A species which has ability to donate proton is known as an acid whereas a species which has ability to accept proton is known as a base.

The reaction of acids and bases results in the formation of salts and this reaction is known as neutralization reaction.
