If completely dissociates in water, it means it is a dilute strong base.
<h3>What is a base?</h3>
A base is a substance that can neutralize the acid by reacting with hydrogen ions.
An acid is a substance that donates hydrogen ions and a base is a substance that accepts hydrogen ions.
Ca(OH)₂ does not have hydrogen ions to donate, but it can accept hydrogen ions to form H₂O according to this equation:
H⁺ + OH⁻ → H₂O.
Hence, Ca(OH)₂ is a base.
A strong base is a base that dissociates completely into metallic and hydroxide ions in aqueous solutions, while a weak base dissociates partially.
Hence, Ca(OH)₂ is a strong base.
Dilute refers to a solution meaning that the substance is not pure and the concentration is low. Since the solution the Ca(OH)₂ is 0.02 M means that it is diluted.
Therefore, we have found that the description of 0.02 M Ca(OH)₂ is a dilute strong base.
