The open circles show the chromaticity of light reflected from a plaque of barium sulfate.
Liquid suspensions of barium sulfate are non-toxic, apart from a small risk of producing a disturbance in bowel function for 48 hours after ingestion.
Barium sulfate is used in some applications too.
An exception is the administration of magnesium sulfate in barium chloride poisoning, where sulfate binds to barium to form insoluble barium sulfate.
The brightening occurs because barium sulfate is in the form of a fine precipitate that scatters light back through the silver image layer.
Shortly after, the process was improved; barium was removed chemically, by double precipitation from a solution as barium sulfate.
The paste contains carbon black, "blanc fixe" (barium sulfate) and lignosulfonate.
In colorimetry barium sulfate is used as a near-perfect diffuser when measuring light sources.
Managing Your Emotions
What makes me angry?
Mostly，l hate when someone tries to make someone else feel bad.
I have to admit that once, when l was actually called names.
l regretted doing this afterwards, but not full heartedly because l think l was provoked in that situation.
The most postive way of dealing with anger is talking about the problem.
l talk to someone who listens, or l'll write my thoughts down on paper.
Learning how to deal with anger as you're growing up is so important.
When you're younger, you might yell,or cry when you're angry, but as you get older, you're expected to handle your emotions much better.
Learning to control your emotion now will prevent you from doing something that you'll regret later on in life!
