Hi there.
00:04
This question is asking about a solid precipitate and the formation of that precipitate.
00:10
Let's talk for a moment about what a precipitate is.
00:18
A precipitate refers to solid particles that are formed when two clear solutions are mixed together.
00:41
Notice this definition says nothing about color, but it talks about solid particles forming when two clear solutions are mixed together.
00:49
Mixed.
00:50
There could be color.
00:53
Typically, the precipitate will express itself as having a color.
00:59
It can be white, it can be yellow, and so forth.
01:04
But the important thing is that they are solid particles.
01:07
And these solid particles are suspended in the solution.
01:17
Over time, they may settle to the bottom, but you're never going to get just one large chunk of solid.
01:24
So that eliminates two of our answers.
01:27
A and d are eliminated because we're not going to get a large chunk...
