What is the name of the solution to test for acids or alkalis?
There are various ways to test for an acid and an alkali. For acidic solution: Litmus paper/ litmus solution --> red Phenolphthalein --> colorless Methyl orange --> pink Universal Indicator (changes color according to the strength of acid) --> red to yellow. For alkaline solutions: Litmus paper/ litmus solution --> blue Phenolphthalein --> pink Methyl orange --> yellow Universal Indicator --> blue green to purple
Do acids turn universal indicator solution green?
Universal Indicators vary slightly, so always consult the colour chart provided by the manufacturer, but acids tend to give reds, oranges and yellows.

How are acids and bases tested?
universal indicator or litmus paper
Do universal indicator acids have a sharp or sweet or blunt taste?
no
What makes universal indicator paper turn red?
acids
How do you make a universal indicator?
Universal indicator is an aqueous solution of many indicators: methanol, propan-1-ol, phenolphthalein sodium salt, methyl red and monosodium salts of bromothymol blue and thymolblue. Most of these have a very complicated process associated with it during its manufacture.
What colour an alkali comes out with a universal indicator?
Blue/Violet/Indigo . depending on the strength of the alkali. Water (neutral ) is green Acids ' Red/Orange/Yellow.
When universal indicator solution is added to vinegar it turns what color?
It will turn a yellowish orange due to the acetic acid in vinegar. Carboxylic acids are weak by nature.
How can hydrochloric acid turn red in color?
Universal Indicator turns concentrated HCl red because Universal Indicator turns strong acids reds.
What are some property's of acids?
Sour taste, reactivity with metals, and ability to produce color changes in indicators. They sour and reacts with metal, metal carbonate and bases/alkali. Most of them are corrosive as well. They can change the color of objects like universal indicator (depending on pH, stronger acids will turn universal indicator red while the weaker ones will only turn universal indicator to yellow or orange) and moist blue litmus paper red.
