What masses of sodium chloride, magnesium chloride, sodium sulfate, calcium chloride, potassium chloride, and sodium bicarbonate are needed to produce 1 L of artificial seawater for an aquarium? The required ionic concentrations are (Na+) = 2.56 M, (K+] = 0.0090 M, [Mg2+] = 0.054 M, [Ca2+] = 0.010 M, [HCO3−] = 0.0020 M, [Cl−] = 2.60 M, [SO42-] = 0.051 M.

Interpretation:
Masses of Sodium chloride, Potassium chloride, Sodium sulphate, Calcium chloride, Magnesium chloride and Sodium bicarbonate are required to produce 1L of artificial sea water has to be calculated.
Concept introduction:
Mass is the determination of the quantity of the matter in an object. Unit of mass is gram (g) or kilogram (kg). Mass is calculated by multiplying the volume of the compound into its density.
Answer to Problem 13.106QP
Amount of given salts to produce artificial sea water are,
Explanation of Solution
Given data
Required ionic concentrations are,
To calculate the calculation of all ions
To calculate subtotal of sodium and chloride ion
- The subtotal of chloride ion
Since the required concentration of chloride ion is 2.60M, so the difference is,
- The subtotal of Sodium ion
Since the required concentration of Sodium ion is 2.56M, so the difference is,
By adding the sodium and chloride ions concentration, the subtotal respective ions have calculated.
To calculate mass of the compounds required
By plugging in the value of mass of the given compounds and number of moles of the compound, the mass required to produce 1L of artificial sea water has calculated.
Masses of Sodium chloride, Potassium chloride, Sodium sulphate, Calcium chloride, Magnesium chloride and Sodium bicarbonate are required to produce 1L of artificial sea water has been calculated.

- When two solutions, one of 0.1 M KCl (I) and the other of 0.1 M MCl (II), are brought into contact by a membrane. The cation M cannot cross the membrane. At equilibrium, x moles of K+ will have passed from solution (I) to (II). To maintain the neutrality of the two solutions, x moles of Cl- will also have to pass from I to II.
