Sodium Hydroxide – NaOH
Sodium Hydroxide – NaOH
- Sodium hydroxide is utilized to raise the pH of water in a variety of applications. The chemical leaves no residual color, is a high-strength product, and is available at concentrations of 2-50%.
- CAS No. : 1310-73-2
- Chemical Formula : NaOH
- In water Treatment it is used to pH neutralization & Precipitation
- By adding hypochlorite to water, hypochlorous acid (HOCl) is formed: NaOCl + H2O → HOCl + NaOH-
- In the example shown above hydrochloric acid (HCl) is neutralized with caustic (NaOH) and yields ordinary table salt (NaCl) and neutral water. NaCl, being very soluble in water, remains dissolved in solution
