## Indicate the number of equivalents in each of the following molar quantities of ions. a. 1 mole K+ b. 1 mole H2PO4− c. 1 mole HPO42− d. 1 mole Ca2+

(a)

Interpretation Introduction

Interpretation:

Number of equivalents in 1 mol K+ has to be determined.

Concept-Introduction:

Body fluids have small amounts of different type electrolytes and its concentration is measured in equivalents or mill equivalents per liter. An Equivalent (Eq) of an ion is the molar amount of a certain ion required for supplying one mole of negative or positive charge.

Few examples for the relationship between number of equivalent and charge of an ion is given below,

1 mole = 1 equivalent (For ions with charge 1+ or 1)1 mole = 2 equivalent (For ions with charge 2+ or 2)1 mole = 3 equivalent (For ions with charge 3+ or 3)

### Explanation of Solution

Given data is shown below:

No. of moles = 1 molCharge of ion = 1+

Amount of ions needed for supplying one mole of charge is one equivalent

(b)

Interpretation Introduction

Interpretation:

Number of equivalents in 1 mol H2PO4 has to be determined.

Concept-Introduction:

Body fluids have small amounts of different type electrolytes and its concentration is measured in equivalents or milliequivalents per liter. An Equivalent (Eq) of an ion is the molar amount of a certain ion required for supplying one mole of negative or positive charge.

(c)

Interpretation Introduction

Interpretation:

Number of equivalents in 1 mol HPO42 has to be determined.
