The preparation of Mg ( OH ) 2 is to be discussed and the volume of acid required to neutralize 10 ml Mg ( OH ) 2 is to be determined. Concept introduction: The acid-base reaction occurs between an acid and a base. They react to neutralize the acidic and basic nature of compounds to form salts and water. Acids and bases also react with metals. The number of moles of a reactant is calculated by the following formula: m = w t M W Here, m is the number of moles of the compound, w t is the weight of the compound, and M W is the molecular weight of the compound. The concentration of a solution in terms of molarity is determined as follows: M = ( m ) ( 1 V ) Here, M is the concentration of the compound in molarity, m is the number of moles of the compound, and V is the volume of solution in litre containing the compound.

Concept introduction:
The acid-base reaction occurs between an acid and a base. They react to neutralize the acidic and basic nature of compounds to form salts and water. Acids and bases also react with metals.
The number of moles of a reactant is calculated by the following formula:
m=wtMW
Here, m is the number of moles of the compound, wt is the weight of the compound, and MW is the molecular weight of the compound.
The concentration of a solution in terms of molarity is determined as follows:
M=(m)(1V)
Here, M is the concentration of the compound in molarity, m is the number of moles of the compound, and V is the volume of solution in litre containing the compound.

How to measure distance and calculate rate
For the titration of a divalent metal ion (M2+) with EDTA, the stoichiometry of the reaction is typically:
1:1 (one mole of EDTA per mole of metal ion)
2:1 (two moles of EDTA per mole of metal ion)
1:2 (one mole of EDTA per two moles of metal ion)
None of the above
