(a)
Interpretation:
The number of milliequivalents of Na+ ions in 1 L of solution is to be calculated.
Concept introduction:
One equivalent of an ion can be defined as the amount of charge an ion contributes when present in dissolved form. For example, one mole of Mg2+ contributes 2 equivalent of Mg2+ ions as the charge is +2 . Similarly, one mole of SO42− contributes 2 equivalent of SO42− ions as the charge is −2.
Conversion factors are utilized for the conversion of one unit into another unit.
(b)
Interpretation:
The number of milliequivalent of Na+ ions in 2 L of solution is to be calculated.
Concept introduction:
The concentration of an ion in solution is expressed in equivalents.
One equivalent of an ion can be defined as the amount of charge an ion contributes when present in dissolved form. For example, one mole of Mg2+ contributes 2 equivalent of Mg2+ ions as the charge is +2 . Similarly, one mole of SO42− contributes 2 equivalent of SO42− ions as the charge is −2.
Conversion factors are utilized for the conversion of one unit into another unit.
(c)
Interpretation:
The number of milliequivalent of Na+ ions in 440 mL of solution is to be calculated.
Concept introduction:
The concentration of an ion in solution is expressed in equivalents.
One equivalent of an ion can be defined as amount of charge an ion contributes when present in dissolved form. For example, one mole of Mg2+ contributes 2 equivalent of Mg2+ ions as the charge is +2.
The conversion factor to convert mL to L is given as follows:
1 mL=10−3 L
Conversion factors are utilized for the conversion of one unit into another unit.
