(a)
Interpretation:
The mass percentage each ion in the seawater is to be calculated.
Concept introduction:
Mass percent is defined as the mass of a component divided by the total mass of the mixture multiplied by 100.
The expression to calculate the percentage mass of ions is as follows:
(b)
Interpretation:
Percentage of the total mass of ions represented by sodium ions is to be calculated.
Concept introduction:
Mass percent is defined as the mass of a component divided by the total mass of the mixture multiplied by 100.
The expression to calculate the percentage mass of ions is as follows:
(c)
Interpretation:
The total mass
Concept introduction:
Mass percent is defined as the mass of a component divided by the total mass of the mixture multiplied by 100.
The expression to calculate the percentage mass of ions is as follows:
The alkali metal is defined as the group of elements that are found in Group I. The alkaline earth metal is defined as the group of elements that are found in Group II.
(d)
Interpretation:
The cation or anion that has larger mass fraction of dissolved component is to be identified.
Concept introduction:
Mass percent is defined as the mass of a component divided by the total mass of the mixture multiplied by 100.
The expression to calculate the percentage mass of ions is as follows:
Ions that are formed by the loss of electrons form a positively charged ion. The positively charged ions are called cation.
Ions that are formed by the gain of electrons form a negatively charged ions. The negatively charged ions are called anion.
