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.
Universal indicator turns shades of blue or purple in an alkali.
Bromine turns a yellow-brown color when mixed with universal indicator.
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.
Universal indicator paper will turn blue or blue-green when dipped into ammonia solution, indicating that the solution is basic or alkaline.
It goes purple
When an alkali is added to a test tube containing Universal Indicator, it typically turns the indicator solution a dark green or blue color. This is because Universal Indicator is a mixture of different pH indicators that show a range of colors from red (acidic) to green (neutral) to blue or purple (alkaline). The specific color change observed may vary depending on the concentration and type of alkali used.
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.
A Universal indicator is a pH indicator composed of a solution of several compounds that exhibits several smooth colour changes over a pH value range from 1-14 to indicate the acidity or basicity of solutions. A universal indicator is typically composed of water, propan-1-ol, phenolphthalein sodium salt, sodium hydroxide, methyl red, bromothymol blue monosodium salt, and thymol blue monosodium salt.
it goes bluey purpley when it is in water and red in acid and yellow - green in alkali
One common indicator of acids and bases is litmus paper. Litmus paper turns red in acidic solutions and blue in basic solutions. Another indicator is phenolphthalein, which is colorless in acidic solutions and pink in basic solutions.
