I think this should have been in the beginnings section. Common indicators in the lab are litmus, methyl orange, phenolphthalein, etc. There are
resources on the internet that will tell you this without having to open another thread here. Please do some research before posting.

You don't seem to know much of chemistry if you have to ask a basic question like that.
Litmus, the most common, is blue at high pH---the rest you can guess at. . .
You, I think, have a lot of reading to do.
