Reason : The acidity of a base is equal to the number of hydroxyl ions.

  • a)
    Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).

  • b)
    Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).

  • c)
    Assertion (A) is true but reason (R) is false.

  • d)
    Assertion (A) is false but reason (R) is true.

The number of replaceable hydroxyl (OH) Ions in a base is called the acidity of that base. Magnesium hydroxide has 2 replaceable hydroxyl ions, therefore it's acidity is 2. Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A)

First of all here acidity is incorrect it is acicity which is the no of replaceable OH ion is known as acicity of base similarly basicity of acid no. of replaceable H ion. so i hope you all guy's understand the matter thank you

Assertion: The acidity of Mg(OH)2 is two.
Reason: The acidity of a base is equal to the number of hydroxyl ions.

Explanation:

The acidity of a substance refers to its ability to release hydrogen ions (H+) in water. Acids are characterized by their sour taste, ability to turn blue litmus paper red, and their ability to react with bases to form salt and water.

On the other hand, bases are substances that can accept hydrogen ions or donate hydroxide ions (OH-) in water. Bases have a bitter taste, turn red litmus paper blue, and react with acids to form salt and water.

In the case of Mg(OH)2, it is a base because it contains the hydroxide ion (OH-) as a component. When it dissolves in water, it releases hydroxide ions (OH-), which can accept hydrogen ions (H+) to form water.

Now let's analyze the given assertion and reason:

Assertion: The acidity of Mg(OH)2 is two.
Reason: The acidity of a base is equal to the number of hydroxyl ions.

The assertion states that the acidity of Mg(OH)2 is two. This means that when Mg(OH)2 dissolves in water, it releases two hydroxide ions (OH-) per molecule.

The reason given for this assertion is that the acidity of a base is equal to the number of hydroxyl ions. This statement is correct because bases release hydroxyl ions (OH-) in water, and the number of hydroxyl ions released determines the acidity of the base.

Therefore, both the assertion and reason are true, and the reason correctly explains the assertion. The correct answer is option 'A': Both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).
