Last week we used acids, alkali, and water to find out if they had the things in them. Indicators can help us to do a lot of things like check if the waters good because if you put the universal indicator in water if it was normal and good water it would turn green. The cranberry juice had a slight color change with the water and the acid. The tea acid turned the tea orange water orange alkali turned it dark red and the turmeric acid yellow alkali red water yellow.
