## What is the concentration of 50\% NaOH?

Therefore, we can say that 1 liter of sodium hydroxide solution contains 18.9375 moles or in other words molarity of 50\% (w/w) Sodium Hydroxide is equal to 18.9375 M….Known values.

Known values | |

Concentration of Sodium Hydroxide solution | 50\% (\% by mass, w/w) |

Density of 50\% (w/w) Sodium Hydroxide solution | 1.515 g/ml |

**How do you make 40 percent NaOH?**

To prepare a 40\%NaOH solution you weigh 40 gm NaOH and dissolve it in 100 ml water. To prepare 1 M you dissolve the molecular weight of it in one L. The molecular weight of NaOH is 23+16+1=40 gm. Hope this helps!

**How do you make a 60 NaOH solution?**

Normally, solution percentages are defined as weight(solute)/weight(solution) or weight(solute)/volume(solution). So 60\% NaOH solution should be 60g NaOH and 40g H20 (if w/w) or filling up 60g NaOH with water until you reach a total volume of 100mL (if w/v).

### How do I make a 50\% KOH solution?

50\% KOH means half quantity KOH diluted in equal quantity of water.. For example if we want to make 10 ml solution of KOH then we’ll add 5 ml water to 5 ml concentrated KOH to make a 50\% KOH solution..

**Which is the best method for determining the concentration of NaOH solution?**

titration

One method for concentration determination of sodium hydroxide solutions is titration, where correct and precise results are neither trivial nor quick. Besides, the operator is exposed to the caustic sample.

**How do you prepare NaOH?**

It is generally prepared by electrolysis of sodium chloride in Castner-kellner cell. A brine solution is electrolyzed using mercury cathode and carbon anode. Sodium metal, discharged at the cathode, combine with mercury to form sodium amalgam.

## How would you prepare a 5\% solution of NaOH?

Therefore, from Mass by Volume percentage concept we can say that 5\% NaOH solution (W/V) means 5g of NaOH dissolved in 100ml of water.

**What is a 50\% solution?**

This is used when both chemicals in a solution are liquid. For example, when 50ml of sulphuric acid is diluted with 50ml of water, there will be 50ml of sulphuric acid in a total volume of 100ml. Therefore, we would express the concentration of this solution as sulphuric acid 50\% v/v.

**How do you make a 40 solution?**

To make 40 mM solution, you should dilute 30\% solution 245 times, i.e. mixing of 1 mL of 30\% H2O2 with 244 ml of H2O will give you 245 mL of 40 mM H2O2.
