The concentration of sodium ions in the diluted solution is .
Further Explanation:
The concentration is the proportion of substance in the mixture. The most commonly used concentration terms are as follows:
1. Molarity (M)
2. Molality (m)
3. Mole fraction (X)
4. Parts per million (ppm)
5. Mass percent ((w/w) %)
6. Volume percent ((v/v) %)
Molarity is a concentration term that is defined as the number of moles of solute dissolved in one litre of the solution. It is denoted by M and its unit is mol/L.
The molarity equation for the dilution of solution is as follows:
......(1)
Here,
is the molarity of the initial solution.
is the volume of the initial solution.
is the molarity of the diluted solution.
is the volume of the diluted solution.
Rearrange equation (1) to calculate .
......(2)
The value of is 0.765 M.
The value of is 25 mL.
The value of is 225 mL.
Substitute these values in equation (2).
Dilution is the conversion of a concentrated solution into a dilute solution with the addition of extra solvent but the amount of solute is unaltered. The change that arises is an increase in the volume of the solution.
The dissociation of occurs as follows:
According to the balanced chemical equation, one mole of dissociates to form two moles of . So the concentration of can be calculated as follows:
