How do you test the presence of acid group in tartaric acid?
To test for the presence of an acid group in tartaric acid, you can use litmus paper or pH paper. Dip the paper into a tartaric acid solution; if it turns red, the acid group is present. Additionally, you can perform a titration experiment with a base solution to determine the acidity of tartaric acid.
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
What test can be used to confirm presence of HCl?
One common test to confirm the presence of hydrochloric acid (HCl) is the litmus paper test. When a strip of blue litmus paper is dipped into a solution containing HCl, it will turn red, indicating the presence of an acid. Another test is to use a pH indicator, such as phenolphthalein or bromothymol blue, which will change color in the presence of an acidic solution.
Does sodium carbonate react with phenolphthalein indicator?
Sodium carbonate does react with phenolphthalein indicator, producing a color change from colorless to pink in alkaline solutions. Sodium carbonate is a common base that can be used to test for the presence of acidity or alkalinity in a solution using phenolphthalein.
What acid do you use for the acid test?
For the acid test to determine the authenticity of gold, you typically use nitric acid. Nitric acid is used to test the purity of gold based on the reaction it produces with the metal.

Is tartaric acid gives tollen's test positive?
yes... it gives silver particle deposition at the bottom of test tube
Two tests for reactions that produce acid end products?
Litmus paper test: Dip a strip of litmus paper into the sample solution. If the paper turns red, it indicates the presence of acid. Phenolphthalein test: Add a few drops of phenolphthalein indicator to the solution. If the solution turns pink or red, it indicates the production of acid.
What will happen with each what indicators used to test an acid phenolphthalein?

Which gas will be evolved if Sodium bicarbonate is added to a solution of Tartaric acid. How will you test this gas?
You should get carbon dioxide (CO2). Combining sodium bicarbonate to tartaric acid will yield water-soluble sodium tartrate and carbonic acid. Carbonic acid (H2CO3) will instantly decompose into water and carbon dioxide. Collect the gas, pour it over a lit candle flame. The flame will go out, proving that it's CO2. sodium bicarbonate and Tartaric acid together in dry form are baking powder.
How could you determine whether phenolphthalein remains in the residue of a titration reaction?
The easiest way is to add back some of the solution you were titrating. If phenolphthalein remains, it will react with the solution and change back to purple. Incidentally, phenolphthalein will always remain in the solution of the titration reaction - it changes color depending upon the pH of the solution, but the indicator itself is not affected by the titration reaction.
What is the type of test used to show color changes of certain water solutions?
adding what is called an indicator such as phenolphthalein which is colorless in an acidic solution, but turns pink in an acid solution often used in a test called titration

Test for ester?
Acid hydrolysis using sulphuric acid and water (equilibrium reaction). The ester splits into a carboxylic acid and alcohol, protons donated from the acid. The solution can then be distilled and the remaining acid can be checked using UV indicator. Acid hydrolysis using sulphuric acid and water (equilibrium reaction).

Is it true that calcite and poweder dolomite give same test with cold acid?
yes
What is phenolphthalein?
it is a agar medium for Microbiology containing phenolphthalein biphosphate. It is used in Petri plates and detects the phosphatase character of microbial colonies but requires final addition of alkali to color the phenolphatlein and the color rapidly fades.
