How could you Detect the presence of cl-?
To detect the presence of CI- ion, add silver nitrate solution. A white opalescence to cloudy precipitate of silver chloride will form and confirm the presence of CI- ion.
What was the first living thing that could see?
The oldest recorded organism that had photosensitive sensory organs with the ability to detect the presence and direction of light within a few degrees of accuracy was a prehistoric sea snail that existed approximately 550 million years ago. Organisms that could detect the presence but not the direction of light probably evolved earlier, but no fossils of these organisms have been found.
How could you detect the presence of Cl- ion?

How could you detect the presence of the l negative ion?
Add some kind of substance, and then if this forms or does not form a substance it will prove whether the I negative ion is in the presence.
How could you detect the presence of Ag positive?
A reaction with a halide solution (ex. NaCl) is conclusive; a white precipitate of silver chloride is obtained.
How could you detect the presence of chloride negative ion?
By adding silver nitrate to the compound. If a White precipitate is formed, then it means chloride ion is present.
Is there such thing as a portal gun?
In the game Portal, yes.In real life... there could be something called a portal gun. But there's no known way of making something that works even approximately like the gun in Portal.
Who are chell's parents from portal 2?

Which is better halo reach or portal 2?
Definitely Reach. Portal 2 was just awful. There was absolutely no action. Portal 2 was stupid and I could not get into it. Halo Reach is all action and fun.
How could you detect the presence of the Ag ion?
Silver ions could be detected with the use of a silver ion selective electrode, mass spectrometry, or using certain chemical reactions (ie precipitation when a source of chloride ions is added, complexation using ammonia, etc).
