Test for chlorine gas

[@fernandoduartemolina]

Quick, clear, and to the point! Useful video and beautiful teacher!

It turns red 1st and then white. The colour change is so fast you may not be able to see it.

Very helpful thanks :)

[@louiscullen5857]

not necessarily to be blue litmus paper, just any litmus paper will do. =)
smiling means no offence =)

very cool!

[@AdrianAvendaño-w5i]

Thanks babe, it worked

[@Deadpool-ul1fu]

Why did you moisten litmus paper?

[@ChemJungle]

The reason it bleaches is because of the reaction between the chlorine and the water to make hypochlorite ions - these bleach the colour in the litmus. If there was no water, there would be no reaction!

can i use red litmus paper?

[@RunofRussia5]

I was here for a form!!

[@SupraNathan]

What kind of solution is the testtube

[@dakotahsmith5480]

Any reason why blue litmus paper specifically?

[@ChemJungle]

Normally it's just easier to see the bleaching and the colour change

[@daaimali1193]

you did it the wrong way, dont insert in test tube, just put it right above it

[@fullerz6147]

yeah it shouldn't be in contact with the solution or you could get a false positive

Thank u

Why does the litmus paper turn white in the presence of Cl2?

[@chookers1074]

Because this is chemistry 🌞
