Answer:
The amount of NaOH required to prepare a solution of 2.5N NaOH.
The molecular mass of NaOH is 40.0g/mol.
Explanation:
Since,
NaOH has only one replaceable -OH group.
So, its acidity is one.
Hence,
The molecular mass of NaOH =its equivalent mass
Normality formula can be written as:
Substitute the given values in this formula to get the mass of NaOH required.
Hence, the mass of NaOH required to prepare 2.5N and 1L. solution is 100g
Answer: chemical property.
Explanation:
The chemical properties are the capacity or incapacity of a substance to transform into one or more different substance either by reacting with one or more different substances or by decomposition.
Such properties can only be observed when such change (reaction) takes place and the substance, therefore, is transformed into one or more different substances.
On the other hand, the physicial properties can be observed or measured without changing the composition of the sample.
