How would you prepare a 1 M solution of sodium hydroxide?
How would you prepare a 1 M solution of sodium hydroxide?
To make 1 M NaOH solution, you have to dissolve 40.00 g of sodium hydroxide pellets in 250 mL distilled water and then make up the solution to 1 liter. Weigh 19.95 gm of NaOH pellets & dissolve them in half liter(500ml) of distilled water water, what you will be having now is 1M NaOH solution.
What does 1’m NaOH mean?
One molar (I M) solution means one mole of a substance (solute) per liter of solution. Thus 40 grams of NaOH equals one mole of NaOH, and a 1 molar solution of NaOH will contain 40 grams of NaOH chemical.
Is 1M NaOH corrosive?
Precautions for safe handling Additional hazards when processed : May be corrosive to metals. Precautions for safe handling : Do not get in eyes, on skin, or on clothing.
What is the pH of 1’m NaOH?
13
The pH of 1M NaOH is 13.
What is the density of 1’m NaOH?
1.02 g/ml
Molarity of 1m aqueous NaOH solution [density of the solution is 1.02 g/ml]: A.
What is the pH value of sodium hydroxide?

What are the health hazards of sodium hydroxide?
The major human health hazard (and the mode of action) of sodium hydroxide is local irritation and/or corrosion on skin and eye irritation/corrosion. Human poisoning cases indicate that a dose of 10 grams orally is fatal 23).
What is the product of sodium hydroxide and sulfuric acid?
A reaction between sulfuric acid and sodium hydroxide is of an acid-base type, or is also known as a neutralization reaction. In this process, both compounds undergo a reaction to neutralize the acid and base properties. The products of this process are salt and water .
Is sodium hydroxide and solid?
Pure sodium hydroxide is a white solid , available in pellets, flakes, granules, and also 50% saturated solution. It is deliquescent and also readily absorbs carbon dioxide from the air, so it should be stored in an airtight container. It is very soluble in water with liberation of heat.
