You know the solution forms a precipitate when?
(A) when it changes color
(B) when you can’t see through it
(C) because it bubbles
(D) you have stirred it for more than 5 minutes
(E) the solution thickens
solutions are transparent, precipates do not dissolve, cloud the solution, and eventually settle at the bottom.
so is it when you can't see through it or when the solution thickens?
The correct answer is (B) when you can't see through it. When a solution forms a precipitate, it means that a solid substance is being formed and separating from the liquid. This solid substance is called a precipitate. One common characteristic of a precipitate is that it makes the solution appear cloudy or opaque, thus preventing you from seeing through it.
To determine if a precipitate has formed, you can follow these steps:
1. Start with a transparent or translucent solution.
2. Observe the solution carefully.
3. Look for the formation of any solid particles or a hazy appearance.
4. If the solution becomes cloudy or opaque, it indicates the formation of a precipitate.
Remember that the formation of a precipitate relies on the reaction occurring between different chemical substances. Factors such as temperature, concentration, and reactants will determine if a precipitate will form.
