to hydrolysis polysaccharide and oligasaccharide, ketose yields simpler sugar followed by furfural
universal indicator
H2SO4 + Ca ----> CaSO4 + H2 Test for hydrogen gas place a burningsplit above the test tube to get a "pop" sound. The reaction will not be very rigorous unless using a high molarity of sulphuric acid (strong). However fizzing of hydrogen gas and formation of Calcium Sulphate Salt will occur at the bottom of a test tube.
by simply using litmus papers
what acid do you use to test gold
the best way would be 2 use litmus paper. use the color coding on the box but usually blue is for base and red is for acid.

Too strong, try bleach but first do a test spot.

Probably and why would you want to use acid in the first place but yeah more likely then not
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).

Indicators are used to test if something for example whether vinegar is an acid or alkali. Due to the pH scale, 1 - 3 is a strong acid, 4 - 6 is a weak acid, 7 is neutral, 8 - 10 is a weak alkali and 11 - 14 is a strong alkali. Vinegar should turn orange when added with an indicator, with the pH of about 3.
Acid test or litmus test means to try it an see. The acid test of a cake is eating it. The acid test of a new idea is seeing if it works.

If you are testing with Universal Indicator or the Litmus Test it will turn red.
