A neutral solution (pure water) has a pH of 7.
It dissolves in water to give a neutral solution.
Sodium silicate is stable in neutral and alkaline solutions.
The pH scale extends from O to 14, with a value of 7 indicating a neutral solution (figure 4.1).
In chemistry, a neutral solution is neither acidic nor alkaline.
When the pink colour disappears indicates a neutral, or weakly acidic solution has been created.
Chlorine gas only exists in a neutral or acidic solution.
At 25 C, considered the standard temperature, the pH value of a neutral solution is 7.0.
It is bluish green in neutral solution.
However, it is rather stable in contact with neutral and alkaline aqueous solutions.
