If your water system is one that does water softening, than the sodium Hydroxide (also called caustic soda or lye) would be used to raise the PH before going into a softening tank. With a higher PH the mineral in the water will stick to something like sand that is added to the tank. The sand will get heaver and can be dropped out. Sodium hydroxide is also used in making soft drinks, chocolate and other foods.
A town may add sodium hydroxide to its water supply to adjust the pH levels of the water, making it less acidic and more alkaline. This helps reduce corrosion in the water distribution system and protect pipes from damage. Sodium hydroxide also helps in water treatment by neutralizing acids and improving overall water quality.

Can I lower the pH of sodium hydroxide with water?
No, adding water to sodium hydroxide will not lower the pH. Sodium hydroxide is a strong base, and when dissolved in water, it dissociates to produce hydroxide ions, which make the solution more basic. To lower the pH of a sodium hydroxide solution, you would need to add an acid to neutralize the base.
How do you make a 5 percent water solution of sodium hydroxide?
To make a 5% water solution of sodium hydroxide, you would mix 5 grams of sodium hydroxide with 95 grams of water. This will give you a total of 100 grams of solution, with 5% of it being sodium hydroxide. Remember to always add the sodium hydroxide to the water slowly and with caution due to its caustic nature.
When sodium hydroxide dissolve in water estimate the temperature change when the amount sodium hydroxide is doubled?
When sodium hydroxide dissolves in water, it undergoes an exothermic reaction, releasing heat. If the amount of sodium hydroxide is doubled, the same amount of heat will be released, resulting in an increase in temperature. The specific temperature change would depend on the initial amounts and concentrations of the sodium hydroxide and water.
Is sodium hydroxide in water a suspension?
No, sodium hydroxide in water forms a homogeneous mixture because the sodium hydroxide dissolves in water to form a clear, colorless solution. A suspension would be a mixture where the particles of one substance are dispersed in another but do not dissolve.
When nitric acid and sodium hydroxide are added together sodium nitrate is produced would the sodium nitrate react with the water instantly to form sodium hydroxide again?
No, sodium nitrate does not react with water to form sodium hydroxide. The reaction between nitric acid and sodium hydroxide produces sodium nitrate and water as products. The sodium nitrate remains in its form and does not spontaneously convert back to sodium hydroxide when exposed to water.
If you were to make sodium hydroxide from an oxide what oxide would you use?
Sodium hydroxide (NaOH) is formed.
Is copper soluble in sodium hydroxide?
Metallic copper does not react with sodium hydroxide. But if sodium hydroxide is added into a solution of copper ions, it would form Copper(II) Hydroxide. It is a precipitate which is insoluble in water.
Can I lower the pH of sodium hydroxide with water?
No, adding water to sodium hydroxide will not lower the pH. Sodium hydroxide is a strong base, and when dissolved in water, it dissociates to produce hydroxide ions, which make the solution more basic. To lower the pH of a sodium hydroxide solution, you would need to add an acid to neutralize the base.

What is added to sodium hydroxide that will get sodium sulphate and water?
Sodium sulfate is produced by reacting sulfuric acid with sodium hydroxide. Water is also formed as a byproduct of this neutralization reaction.
Is sodium hydroxide in water a suspension?
No, sodium hydroxide in water forms a homogeneous mixture because the sodium hydroxide dissolves in water to form a clear, colorless solution. A suspension would be a mixture where the particles of one substance are dispersed in another but do not dissolve.

No, sodium nitrate does not react with water to form sodium hydroxide. The reaction between nitric acid and sodium hydroxide produces sodium nitrate and water as products. The sodium nitrate remains in its form and does not spontaneously convert back to sodium hydroxide when exposed to water.
What happens when sulphuric acid reacts with sodium hydroxide?
When sulfuric acid reacts with sodium hydroxide, a neutralization reaction occurs producing water and sodium sulfate as products. The balanced chemical equation for this reaction is: H2SO4 + 2NaOH -> 2H2O + Na2SO4.
If solid sodium hydroxide were added to neutralize the HCl would this reverse the reaction and cause the sodium chloride to redissolve?
No, adding solid sodium hydroxide to neutralize hydrochloric acid (HCl) would not cause sodium chloride to redissolve. The reaction between sodium hydroxide and hydrochloric acid forms water and sodium chloride, which remains in its dissolved form. The addition of solid sodium hydroxide would simply further neutralize the acid and increase the concentration of the resulting sodium chloride solution.
How many pounds of Sodium Hydroxide does it take to make 10 gallons of 50 percent Sodium Hydroxide solution?
To make 10 gallons of a 50% sodium hydroxide solution, you would need 10 pounds of sodium hydroxide. This is because the percentage indicates the weight of sodium hydroxide in the solution. Hence, in a 50% solution, half of the weight of the solution is sodium hydroxide.
What hazards does sodium hydroxide have?
Sodium Hydroxide (caustic soda or lye) is caustic and as a result it will destroy or irreversibly damage another substance with which it comes into contact including skin!. It is reactive to aluminum so be careful if you are using it to make soap. If you will be working with sodium hydroxide always keep a bottle of vinegar near by since water will not stop the corrosive effects only an acid.
