Actually a 50% solution of sodium hydroxide would be made using enough water to total 100 mL of solution if using sodium hydroxide pellets or crystals. 50% of the total weight of the solution not 50% of the weight of the water used. As suggested by the first answer, the solution would be about a 33% solution. percentage solutions are weight for weight. Therefore 50% solution would be 50g of sodium hydroxide dissolved in 100g (100mL) of water.
To prepare a 30% solution of sodium hydroxide, you would dissolve 30 grams of sodium hydroxide pellets in enough water to make a total solution weight of 100 grams (30 grams NaOH + 70 grams water). Always remember to add the sodium hydroxide to the water slowly and carefully while stirring, as it generates heat when dissolving, and wear appropriate protective equipment such as gloves and goggles.

What is the Method of preparation of 3 percent solution of sodium hydroxide?
To prepare a 3% solution of sodium hydroxide, you can dissolve 3 grams of sodium hydroxide pellets in 100 mL of distilled water. Ensure proper safety precautions are taken when handling sodium hydroxide as it is a caustic substance that can cause burns.
How do you prepare 6n ammonium hydroxide from 30 percent solution?
To prepare a 6N ammonium hydroxide solution from a 30% solution, you would first calculate the molarity of the 30% solution. Then, you would dilute the 30% solution with water to reach the desired concentration. Calculate the volume of the 30% solution needed and dilute it with water to reach the final volume for a 6N concentration.
How do you prepare a 30 percent NaCl solution?
To prepare a 30% NaCl solution, you would dissolve 30 grams of table salt (NaCl) in enough water to make a total solution volume of 100 mL. This would result in a 30% concentration of NaCl in the final solution.
What is the relative formula mass of Sodium hydroxide?
The relative formula mass of Sodium hydroxide (NaOH) is 40 g/mol. This is calculated by adding the atomic masses of sodium (23 g/mol), oxygen (16 g/mol), and hydrogen (1 g/mol).
How prepare 6N ammonium hydroxide?
To prepare 6N ammonium hydroxide, you would need to calculate the amount of ammonium hydroxide required based on its concentration. For example, to prepare 1 liter of 6N ammonium hydroxide, you would mix approximately 576 mL of concentrated ammonium hydroxide solution (28-30% NH4OH) with water to make up a total volume of 1 liter. Remember to handle the concentrated solution with care, as it can be corrosive.

What is the relative formula mass of Sodium hydroxide?
The relative formula mass of Sodium hydroxide (NaOH) is 40 g/mol. This is calculated by adding the atomic masses of sodium (23 g/mol), oxygen (16 g/mol), and hydrogen (1 g/mol).
How do you prepare 30mL of 1 M NaOH solution?
To prepare 30mL of 1 M NaOH solution, measure 30mL of distilled water and slowly add solid NaOH while stirring until 1 mole of NaOH has completely dissolved. Ensure the final volume is 30mL by adding more water if needed. Remember to handle NaOH with care and wear appropriate personal protective equipment due to its caustic nature.
