What coulor do alkalis turn universal indicator?
Alkalis turn universal indicator blue or purple.
What colour do alkalis turn universal indicator?
Alkalis turn universal indicator blue or purple.
What effect does and alkali have on an universal indicator?
When an alkali is added to universal indicator, the color of the indicator will typically change to blue or purple, indicating a high pH. Alkalis are substances that have a pH above 7 and tend to turn universal indicator towards the blue end of the spectrum.
What color does base turn a universal indicator?
The color of a universal indicator in a basic solution is usually purple or blue.
Alkalis turn paper blue?
Alkalis turn red litmus paper blue by converting the indicator dye to its basic form, which has a blue color. This color change occurs due to the increase in pH caused by the alkalis.

Alkalis turn universal indicator blue or purple.
What colour do alkalis turn universal indicator?
Alkalis turn universal indicator blue or purple.
Do alkalis make a universal indicator turn green?
The alkali makes a universal indicator turn blue.

What color do neutral solution turn the unniversal indicator?
A neutral solution will turn universal indicator green.
What colour should sodium be in universal indicator?
Purple. Sodium Hydroxide is an Alkali/base. Bases and Alkalis have a pH greater than 7, and turn blue-purple in universal indicator.
What substance will make universal indicator turn orange?
An acidic substance will turn universal indicator orange. This occurs because universal indicator contains a mixture of dyes that change color based on the pH of the solution. In an acidic environment, the indicator will shift towards the orange end of the color spectrum.
Which liquid or liquids caused the universal indicator to change colour?
The universal indicator changes color in response to the acidic or basic nature of a solution. Acidic solutions will turn the indicator to a red color, while basic solutions will turn it to a blue or purple color. Different liquids with varying pH levels can cause the universal indicator to change color accordingly.
Does ethanoic acid turn universal indicator purple?
No, ethanoic acid (acetic acid) is a weak acid and will turn universal indicator a different color depending on its pH level. It will likely turn universal indicator red or orange indicating acidity.
What color does the indicator paper turn if the substance is a strong acid?
If you are testing with Universal Indicator or the Litmus Test it will turn red.
