What colour do alkalis turn universal indicator?
Alkalis turn universal indicator blue or purple.
What color do alkalis turn universal indicator?
When universal indicator is put in water soluion of alkalis (base) it indicates significant blue colour.
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 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 coulor does a strong turn full range universal indicator?
A strong base typically turns a universal indicator dark blue or purple, while a strong acid will turn it yellow or red. The color change is dependent on the pH level of the solution being tested.

What color do neutral solution turn the unniversal indicator?
A neutral solution will turn universal indicator green.
Do Acids turn universal indicator solution yellow or red?
Acids turn universal indicator solution red.
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.
What colour does universal indicator turn in dilute hydrochloric acid?
Universal indicator will turn red or pink in dilute hydrochloric acid.
What colour would universal indicator turn in ethanol?
Universal indicator would likely turn red in ethanol, indicating that it is acidic.
What colour will universal indicator turn when mixed with a weak alkali?
Universal indicator will turn purple or blue when mixed with a weak alkali.
