The concentration of hydronium ions is greater than 1 × 10–7 for basic solutions. true false

Answer : The given statement is, false.

Explanation :

Ionic product of water : It is defined as the product of the concentration of hydrogen ion and the concentration of hydroxide ion.

The mathematical expression will be,

When the concentration of hydrogen ion and hydroxide ion are equal then the solution is neutral and the value will be, . And the pH of the solution is, 7.

When the concentration of hydrogen ion is greater than then the solution is acidic in nature. And the pH of the solution is, less than 7.

When the concentration of hydrogen ion is less than then the solution is basic in nature. And the pH of the solution is, greater than 7.

Hence, the given statement is false.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
