50% Sodium hydroxide solution is commercially available and can be purchased from any of the suppliers listed here.
Here we have described a procedure to prepare 10 M (or 10 N) sodium hydroxide (NaOH) solution. A 10 M NaOH solution can be prepared by dissolving 40 g of NaOH (Molecular Weight: 40.00) in water to a final volume of 100 ml. Since dissolution of NaOH in water is a highly exothermic reaction, extreme care must be taken while preparing the solution.
A 50% (w/w) concentrated Sodium hydroxide solution is a clear colorless liquid. It is an aqueous solution of Sodium hydroxide (NaOH). The 100 g of 50% Sodium hydroxide solution contains 50 g of NaOH. To calculate the molarity, one must first calculate how much Sodium hydroxide is present in 1 L of 50% Sodium hydroxide solution. Once we know the amount of Sodium hydroxide present in 1 L solution, we can calculate the molarity of the solution by dividing the NaOH amount by the molecular weight.
