What is the concentration of a solution containing 1.0 g sodium hydroxide in 250 cm3?

0.5 M
The molarity of a solution containing 1.0 g NaOH in 250 mL of water is: 0.5 M.

When 4 gm NaOH dissolved in water and prepare 250 mL solution calculator What is the molarity of this solution?

=0.4mol L-1=0.4M.

What is the amount of NaOH is required to prepare 250 mL of 0.1 M solution given that mol wt of NaOH is 40 g mol?

The molecular weight of NaOH is 40 g/mole. To make 250 mL of a 0.1 M solution you need 4g/4 (250 mL is 1/4 of a liter) mol or 1 g of NaOH.

What happens when caustic soda is dissolved in water?

Sodium hydroxide (NaOH), also known as caustic soda, is an alkali that saponifies acids and fats in the process of making soap. When dissolved in water or neutralized with an acid, caustic soda releases a large amount of heat, enough to ignite combustible materials and the aqueous solution known as lye.

How do I calculate the concentration of a solution?

Divide the mass of the solute by the total volume of the solution. Write out the equation C = m/V, where m is the mass of the solute and V is the total volume of the solution. Plug in the values you found for the mass and volume, and divide them to find the concentration of your solution.

How do you make a 10 NaOH solution?

That means you need to dissolve 40 g of NaOH in water to obtain a 1 liter of 1M (or 1N) NaOH solution. To prepare a 10M NaOH solution, you need to dissolve 10 times more NaOH i.e., 400 g of NaOH for 1 L solution.

How many grams of NaOH will be required to prepare 500g solution containing 10 \% ww2 solution?

In 500 g of solution of 10\% w/w NaOH present. So, 25 g of NaOH will be required to prepare 500 g of 5\% w/w NaOH solution.

What happens when sodium hydroxide is mixed in water class 10?

When sodium hydroxide dissolves in water the bond between the sodium and hydroxide breaks leads to the formation of ions. Any reaction associated with the breaking of bonds and leads to new products is known as chemical change. Thus, sodium hydroxide dissolves in water as a chemical change.

What dissolves caustic soda?

Caustic soda is alkaline and vinegar is acidic, so it makes sense at first glance to pour vinegar into the drain and let it react with the hardened material to produce a salt that is far less harmful and will dissolve in water.

What is the molar mass of NaOH in caustic soda?

=> we have 10/ 20 = 0.5 mole of Na OH. Caustic soda…implies NaOH, molar mass of which is 40 grams… Thus, when 40g of NaOH is dissolved in 1 litre (1000 cm3) of water, resulting solution is 1 molar….

Can You dilute caustic soda?

Caustic soda is a solid, NaOH. It is usually used in aqueous solution, which can be made weaker with water. No other fluid would really be appropriate for diluting it. Caustic soda is highly caustic and requires care in handling. “Add water to lye and you may die!”

What happens when 40g of NaOH is dissolved in 1000 cm3 of water?

Thus, when 40g of NaOH is dissolved in 1 litre (1000 cm3) of water, resulting solution is 1 molar…. 10g = 250 *? M Cross multiply….

How much HCl is dissolved in 50 ml of solution?

(c) 0.365 g of pure HCl gas is dissolved in 50 mL of solution. (a) 4 g of caustic soda is dissolved in 200 mL of the solution. (b) 5.3 g of anhydrous sodium carbonate is dissolved in 100 mL of solution. (c) 0.365 g of pure HCl gas is dissolved in 50 mL of solution.
