How do you make a 60% solution?
To prepare 60% solution (weight by volume basis) of a salt you have to dissolve 60 g salt in 100 ml water. But to prepare solution of a given molarity, say to prepare 1 M KOH solution, you have to dissolve 56 g KOH (mol. wt. of KOH is 56) in distilled water and make the final volume to 1 litre.
What is the molarity of 50 NaOH?
Is 50 sodium hydroxide corrosive?
Sodium hydroxide is very corrosive. It is generally used as a solid or a 50% solution. Other common names include caustic soda and lye. Sodium hydroxide is used to manufacture soaps, rayon, paper, explosives, dyestuffs, and petroleum products.
How do you make 40% NaOH?
You will need to dissolve 40 g of NaOH in 900 ml of distilled water, and then adjust the volume to 1000 mL. Beware, the reaction is exergonic and will release heat.
What is the molarity of 40% NaOH?
12M
Molarity of 40% NaOH (w/w) solution is 12M.
How do you prepare 40 NaOH?
How do you make a 30% solution?
You want to end up with 100ml of liquid, 30% of which is alcohol. 30% of 100ml is 30/100 100 = 30 ml. Thus you need 30 ml of alcohol and 70 ml of water.
How do I make a 50 sugar solution?
50% (w/v) Glucose solution
- Prepare ml of 50% (w/v) glucose solution by mixing g of glucose monohydrate with H2Obidest. Be careful not to add too much water at the beginning. The Glucose dissolved better if the solution is slightly warmed (Microwave, heating plate).

How do you make a 40 percent NaOH solution?
What is the molarity of 37% HCl?
12 molar
Thus, fuming/concentrated HCl 37% is 12 molar (= M = mol/L).
What is sodium hydroxide used for?
Sodium hydroxide is used to produce soaps, rayon, paper, products that explode, dyes, and petroleum products. It can also be used in tasks such as processing cotton fabric, metal cleaning and processing, oxide coating, electroplating, and electrolytic extraction. It is often found in commercial drain and oven cleaners.
What pH is bleach?
pH 11-13
Bleach: pH 11-13 Bleach is one of the most common cleaning supplies in households and commercial settings. This particular product has a pH between 11 and 13. Its high level of alkalinity is what makes it corrosive.
