Answer: Titration
Explanation: Titration is defined as the process where a solution of known concentration is used to determine the concentration of an unknown solution.
Volumetric titrations are usually used for neutralization reactions where an indicator is used to know the acidic or basic nature of solution.
The normality equation used at a point where neutralization occurs during the titration is:
= Normality of acid solution
= volume of acid solution
= Normality of basic solution
= Volume of basic solution
Answer : The correct option is, (1) ions.
Explanation :
According to the Arrhenius concept, an acid is a type of substance which ionizes in water to gives ions (hydronium ions or hydrogen ions) and a base is a type of substance which ionizes in water to gives ions (hydroxide ions).
As we know that KOH is a base which ionizes in water to gives ions (hydroxide ions) and ions.
Hence, potassium hydroxide is classified as an Arrhenius base because KOH contains ions.
