Aqueous solution of calcium nitrate reacted with aqueous potassium hydroxide. Write balanced equation,type of reaction and symbol of state?

The balanced equation for the reaction between aqueous calcium nitrate (Ca(NO3)2) and aqueous potassium hydroxide (KOH) is:

Ca(NO3)2 + 2KOH -> Ca(OH)2 + 2KNO3

This is a double displacement reaction.

The symbol of state for each compound is:

Ca(NO3)2 (aq) + 2KOH (aq) -> Ca(OH)2 (s) + 2KNO3 (aq)

Balanced Equation:

```
Ca(NO₃)₂(aq) + 2KOH(aq) → Ca(OH)₂(s) + 2KNO₃(aq)
```

Type of Reaction:

- Precipitation reaction (forms an insoluble solid called a precipitate)

Symbol of State:

- (aq) = aqueous (dissolved in water)
- (s) = solid
