Describe how you would prepare 100ml solution of 40 brix sucrose

To add 40g of sucrose into 60g of water.

Explanation:

°Brix represents amount of sucrose in an aqueous solution. 1 Degree brix represents 1g of sucrose in 100g of solution.

As you want to prepare 100mL of solution of a 40°brix and assuming a density of the solution of 1g/mL you need 100g of solution (100g = Mass solute + Mass solvent) and 40g of sucrose. That means mass of water must be:

100g = Mass solute (Sucrose) + Mass solvent (Mass water).

100g = 40g + Mass Water

60g = Mass of water.

Thus, to prepare a 40°brix solution you need:

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
