What type of cleaner is sodium hydroxide?
Sodium hydroxide is useful for its ability to alter fats. It is used to make soap and as a main ingredient in household products such as liquid drain cleaners. Sodium hydroxide is usually sold in pure form as white pellets or as a solution in water.
Is sodium hydroxide a base or acid?
Now let’s look at lye, a strong base with the chemical formula NaOH (sodium hydroxide). If we add NaOH to water, it dissociates into Na+ and OH-. The sodiums don’t do anything important, but the hydroxyls make the solution more basic.
Is sodium hydroxide a bleach?
Sodium hypochlorite Sodium hypochlorite is chlorine gas dissolved in sodium hydroxide. This is essentially household bleach. Sodium hypochlorite is a disinfectant that is liquid at room temperature and can be dosed with chemical feed pumps.

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 .
What is the viscosity of sodium hydroxide?
Sodium hydroxide has a characteristic viscosity that adds to its storage difficulties and chemical hazards. At 68°F (20°C), a 50% NaOH solution will have a viscosity rating around 78cp (centipoise; 1cp = 1mPas).
How is sodium hydroxide prepared?
Sodium hydroxide ( NaOH ) is prepared by the salt sodium chloride via electrolysis known as chlor-alkali electrolytic method. In this process chlorine gas is given of at the anode and hydrogen gas at the cathode.
