=
Step 3: Simplify
We have 3 sig figs.
2.45616 × 10²⁵ atoms H ≈ 2.46 × 10²⁵ atoms H
Answer:
When an acid and a base are placed together, they react to neautralise the acid and base properties, thus making a salt.
Explanation:
The compound formed by the caption of the base and the anion of the acid is called a salt.

Explanation:
NaOH is hygroscopic
Explanation:
- A standard solution is a solution of known molarity or concentration.
- Standard solutions are used in determining the stoichiometric amount of desired species in an experiment.
- A solution of NaOH is not a standard solution because NaOH is hygroscopic in nature.
- By this, NaOH absorbs moisture from the atmosphere in considerable amount.
- This implies that one must find an air free environment to store and use the compound and accurately quantify it.
- This is why a solution of NaOH is standardize with a primary standard.
