Red! Sulphuric acid has a pH of about 2.
Universal indicator turns shades of blue or purple in an alkali.
An alkali usually turns purple or blue when in universal indicator. This is because universal indicator contains a mixture of different pH indicators that change color at various pH levels, with blue or purple indicating a high pH level associated with alkalis.
Copper oxide will turn blue or purple when Universal Indicator is put on it.If you found this helpful, please rate me :)
The universal indicator would likely turn purple or violet after reacting with caesium in water. This color change occurs because caesium is an alkaline metal that would make the solution more basic, leading to a shift in the indicator's color towards the purple end of the pH scale.
This is false. When you add a carbonate to universal indicator it's does not turn milky. In actual fact it turns either like thick bubbly layers or stay the same depending on the acid type are using in this situation. Because of chemistry scientists have sussed that there is no acid which can make the universal indicator turn milky. So the answer to the question is no and if you have to put this question into into a trye or false table then this question would go under FALSE because it does not turn milky.
Universal indicator turns shades of blue or purple in an alkali.
It goes purple
red
green
Salt water typically forms a neutral pH solution, so it will likely appear green in universal indicator.
The Universal Indicator would go green which is pH 7.
The universal indicator turns blue or violet in alkaline solutions.
An alkali usually turns purple or blue when in universal indicator. This is because universal indicator contains a mixture of different pH indicators that change color at various pH levels, with blue or purple indicating a high pH level associated with alkalis.
Sodium Chloride a.k.a. table salt or sea salt is neutral and so Universal Indicator will go Green with a Ph 7
Universal indicator paper will turn blue or blue-green when dipped into ammonia solution, indicating that the solution is basic or alkaline.
Dark green (slightly alkaine), Blue (moderately alkaine), purple (strongly alkaline).
The universal indicator goes bright red. I thought it was dark red lol =D i joke! i knew it was bright red. that's what mr. bayes, my science teacher said. he used to be a scientist
