How does sodium hydroxide affect water?
Sodium hydroxide helps stabilize the pH balance of hard water by absorbing water and carbon dioxide. Hard water leads to corrosion of metals, which increases the solubility of toxic elements like copper and lead, further contaminating your water. Some additives also release calcium carbonate, which can affect the free flow ...
Why is alkaline dye used in cotton?
Textile dyeing is made easier with this alkaline as it controls the pH balance of water that is required.
Is soda corrosive or alkaline?
