Molarity = moles of solute/Liters of solution ( 1500 mL = 1.5 Liters )

Molarity = 0.800 moles NaOH/1.5 Liters

= 0.533 M sodium hydroxide

A sodium hydroxide solutin is some amount of sodium hydroxide (NaOH) dissolved in pure water (H2O), written NaOH(aq) or Na+(aq) + OH-(aq) (where aq is the state symbol for aqueous meaning in solution in water). The amount of NaOH in your solution is given by the molarity (M) of that solution, which is equal to the number of moles of NaOH divided by the total volume of the solution.

This depends on the mass of sodium chloride dissolved in a known volume of water.

Sodium hydroxide is a chemical compound. If it is dissolved in water it becomes a very caustic mixture.

When sodium hydroxide (NaOH) is dissolved in water, the ions formed are Na^+ and OH^-. Sodium hydroxide is a strong electrolyte and will ionized completely.

Yes, Sodium Hydroxide forms a stron alkaline solution when dissolved in solvent such as water.Yes. All sodium compounds do.

An aqueous solution of sodium hydroxide will be considerably more alkaline than a solution of the same molarity of sodium acetate. Another way is to add silver nitrate to each. The sodium hydroxide will form a precipitate since silver hydroxide is insoluble. The sodium acetate will not form a precipitate because silver acetate is soluble.

Bleach consists of chlorine gas dissolved in an alkali-solution, such as sodium hydroxide (NaOH). When chlorine is dissolved in an alkalic solution, hypochlorite ions (OCl-) are formed during an autoredox reaction. Chlorine reacts with sodium hydroxide to sodium hypochlorite (NaOCl). This is a good disinfectant with a stable effect.

Sodium hydroxide is not an unknown solution.

No. A sodium hydroxide solution is very basic.

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.

Solid ferric hydroxide, Fe(OH)3, precipitates out of solution. The resulting sodium sulphate remains dissolved.

Lye is a solution of sodium hydroxide or potassium hydroxide dissolved in water. Also known as salts.

The function of sodium hydroxide solution is absorb carbon dioxide.

Sodium hydroxide is an alkaline substance which dissolves in water.

Sodium hydroxide does not have a pH number. The pH of a solution of sodium hydroxide depends entirely on the concentration of it in that solution. To learn how to determine the pH of a sodium hydroxide solution, see the Related Questions links.

Sodium hydroxide is used in furosemide injection assay because sodium hydroxide is pH-control and sodium hydroxide control the solution or the solution in stable.

Molarity means moles per litre. So here you have to divide the moles by 75 and multiply by 1000. 0.5/75*1000, which is 6.667 molar.

Molarity (M) = mols/liters. In this case:M = 2.0 moles / (.200) Liters = 10 Molar.
