Question

When calcium hydroxide powder is placed into a hydrochloric acid solution, aqueous calcium chloride and water are formed?

Answer 1

Step-by-step explanation:

If two compounds chemically react together and upon interchanging their elements with each other is known as a double displacement reaction.

For example,
`Ca(OH)_(2) + 2HCl \rightarrow CaCl_(2) + 2H_(2)O`

In this reaction, OH in
`Ca(OH)_(2)` is replaced by Cl of HCl. As a result,
`CaCl_(2)` is formed.

Therefore, the statement when calcium hydroxide powder is placed into a hydrochloric acid solution, aqueous calcium chloride and water are formed, is true.

Answer 2

Answer: yes, when calcium hydroxide powder is placed into a hydrochloric acid solution, aqueous calcium hydroxide and water are formed.


Step-by-step explanation:


1) Calcium hydroxide is a base whose chemical formula is: Ca(OH)₂

2) Hydrochloric acid is the acid with chemical formula HCl


3) Acids and bases react in a double replacement reaction forming salt plus water: Acid + Base → salt + water


4) The specific chemical equation for these reactants is:


Ca(OH)₂ (s) + 2HCl(aq) → CaCl₂ (aq) + 2H₂O(l)

5) CaCl₂ is calcium chloride, a salt, and H₂O is water
