It will become orange because CO2 is an acid
In ultrapure water the indicator remain unchanged.
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.
A change of color specific for acids, red-brown for Merck pH indicators.
since water is pretty neutral, the water does not change color but the universal indicator does. The universal indicator changes color as per the quantity of deionized water... But it changes to straw color or pale yellow in 50mL of deionized water.
it changes into deep blue colour.
sodium will react violently with water, and end products are sodium hydroxide and hydrogen gas. the universal indicator would turn to around orange(?)
it turns neutral (green)
It first starts as yellow with only the indicator in the water, but when the magnesium is added, it turns green, then blue, and lastly purple
water is pretty neutral in terms of the pH scale, so nothing should happen unless you have poisoned water .It'll turn green if you used universal indicator(pH7), after you added it, the water is posioned you can't drink it
Bright red and the colourless

Caesium recats with water to form caesium hydroxide , a base. the universal indicator woulg change color to be brown/purple depending on the concentration i.e pH. see link
since water is pretty neutral, the water does not change color but the universal indicator does. The universal indicator changes color as per the quantity of deionized water... But it changes to straw color or pale yellow in 50mL of deionized water.
It would turn purple, showing the reaction has taken place.
When universal indicator is put in water soluion of alkalis (base) it indicates significant blue colour.
