What is the ionic equation ?
![Below is the balanced chemical equation from the image, suitable for use on an educational website:
**Chemical Equation:**
\[ 3 \text{CaCl}_2 (\text{aq}) + 2 \text{K}_3\text{PO}_4 (\text{aq}) \rightarrow 6 \text{KCl} (\text{aq}) + \text{Ca}_3(\text{PO}_4)_2 (\text{s}) \]
**Explanation:**
This equation represents a double displacement reaction where calcium chloride (\(\text{CaCl}_2\)) reacts with potassium phosphate (\(\text{K}_3\text{PO}_4\)). In aqueous solution, these compounds exchange partners to form potassium chloride (\(\text{KCl}\)) and calcium phosphate (\(\text{Ca}_3(\text{PO}_4)_2\)).
- \( \text{CaCl}_2 \) and \( \text{K}_3\text{PO}_4 \) are both in aqueous form, denoted by \((\text{aq})\).
- \( \text{KCl} \) is also aqueous.
- \( \text{Ca}_3(\text{PO}_4)_2 \) is solid, indicated by \((\text{s})\).
This type of reaction is commonly used in chemistry to demonstrate the formation of a precipitate from two aqueous solutions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa7d7525f-9c27-4dea-8079-91e82ba48598%2F65c27fe9-5691-486c-9a86-d6e75edac0b0%2F1vr4fv_processed.jpeg&w=3840&q=75)
