Consider two beakers of pure water at different temperatures. How do their pH values compare? Which is more acidic? More basic? Explain.
Interpretation Introduction
Interpretation: The two beakers of pure water at different temperature are considered. The pH value of pure water at different temperature is to be compared and more acidic and more basic water is to be identified.
Concept introduction: The scale that provides convenient way to represent solution acidity is known as pH scale.
Water is an amphoteric substance. Auto ionization of water produces a hydronium ion as well as a hydroxide ion.
Explanation of Solution
Explanation
To determine: The comparison of pH values of pure water at different temperatures: more acidic and more basic pure water.
The pH values of pure water at different temperatures remain same.
The pH value of pure water is
Therefore, pH value of pure water at any temperature remains same.
The solution that contains more number of hydronium ion is more acidic and that contains more number of hydroxide ion is more basic
