Let's break down the given chemical equation step-by-step to solve the problem:

[tex]\[ \text{Ca(OH)}_2 + 2\text{HCl} \rightarrow \text{CaCl}_2 + 2\text{H}_2\text{O} \][/tex]

The reaction involves the following substances:

- [tex]\(\text{Ca(OH)}_2\)[/tex]: This is Calcium Hydroxide. It is well known as a strong base in chemistry.
- [tex]\(\text{HCl}\)[/tex]: This is Hydrochloric Acid. It is a strong acid.
- [tex]\(\text{CaCl}_2\)[/tex]: This is Calcium Chloride. As this compound is formed from the neutralization of an acid and a base, it is considered a salt.
- [tex]\(\text{H}_2\text{O}\)[/tex]: This is water, commonly formed in neutralization reactions.

To determine which statement is true about the equation, let's identify each substance's role in the reaction:

1. Ca(OH)[tex]\(_2\)[/tex]: We identified Calcium Hydroxide as a base.
2. HCl: We identified Hydrochloric Acid as an acid.
3. CaCl[tex]\(_2\)[/tex]: We identified Calcium Chloride as a salt.
4. H[tex]\(_2\)[/tex]O: A product of the neutralization reaction, commonly known as water.

Based on this analysis, we have established that:

- [tex]\(\text{Ca(OH)}_2\)[/tex] is the base.
- [tex]\(\text{CaCl}_2\)[/tex] is the salt.

Therefore, the correct statement about the equation is:

[tex]\[ \text{Ca(OH)}_2 \text{ is the base and } \text{CaCl}_2 \text{ is the salt.} \][/tex]

Thus, the correct option is:

[tex]\[ 1. \text{Ca(OH)}_2 \text{ is the base and } \text{CaCl}_2 \text{ is the salt.} \][/tex]
