Add an alkaline (base) to it. Examples: Soda Ash, Baking Soda
Water is neutral, with a pH of 7. It is neither acidic nor basic.
Tap water is typically neutral, meaning it is neither basic nor acidic.
SeO3 would be acidic, tending to make selenic acid H2SeO4
Tap water is only slightly acidic
basic. 0-7 is acidic and 7-14 is basic
Acidic gas :)
Acidic property
Acidic oxides react with water to form acids, while basic oxides react with water to form bases. Acidic oxides have a higher concentration of oxygen ions, leading to a more acidic solution when dissolved in water. Basic oxides have a higher concentration of metal ions, resulting in a more basic solution when dissolved in water.
Tap water is typically considered to be neutral, meaning it is neither acidic nor basic.
Acidic
It is practically slowly acidic
Rain water is generally acidic
