When washing soda (sodium carbonate) is dissolved in water, it creates an alkaline solution. The universal indicator would turn blue to purple, indicating a pH level typically above 9. This color change signifies the basic nature of the washing soda solution.
Salt water typically forms a neutral pH solution, so it will likely appear green in universal indicator.
it changes into deep blue colour.
Pure water is neutral so the color will be green.
Water is NOT Universal Indicator. Water is often referred to as a Universal Solvent as a large number of substances are soluble in it. Universal Indicator is a chemical agent that can be used to test the pH of a liquid.
If universal indicator is added to water after a reaction with cesium, the solution would likely turn purple or dark blue. This is because cesium reacts vigorously with water to produce cesium hydroxide, which is a strong base. The formation of this alkaline solution raises the pH, causing the universal indicator to shift toward the color that corresponds to higher pH levels.
Water typically turns green in universal indicator. This indicates that water is neutral, neither acidic nor basic.
Salt water typically forms a neutral pH solution, so it will likely appear green in universal indicator.

When universal indicator is put in water soluion of alkalis (base) it indicates significant blue colour.
it changes into deep blue colour.
Pure water is neutral so the color will be green.
Universal indicator will change to a bleaching effect color (yellow or yellow-green) when chlorine water is added due to the presence of hypochlorous acid.
Water is NOT Universal Indicator. Water is often referred to as a Universal Solvent as a large number of substances are soluble in it. Universal Indicator is a chemical agent that can be used to test the pH of a liquid.
Soap typically appears pink in universal indicator due to its slightly alkaline nature. The pink color indicates a pH level around 8-9 when soap is dissolved in water.
Copper oxide will turn blue or purple when Universal Indicator is put on it.If you found this helpful, please rate me :)
When you dissolve copper oxide in water and add universal indicator, the solution will most likely turn blue or green. The exact color can vary depending on the pH level of the solution.
A slightly acidic water sample would likely result in a universal indicator displaying a color in the green range, indicating a slightly acidic pH level around 6 or 6.5.
