7. What must never be tested for acid and base?
Answer:
Acid
Explanation:
Acids turn litmus paper red, while bases turn litmus paper blue. A neutral chemical won't change the paper's color. Because they separate into ions in water, both acids and bases conduct electricity. ... However, since both acids and bases can be corrosive, you shouldn't test chemicals by tasting or touching them!

Answer:
what is the texture of acid? sticky
what is the texture of base?slippery
what is the corrosive of acid?hydrochloric
what is the corrosive of base?ammonium hydroxide
what is the conductivity of acid?chemdemos
what is the conductivity of base? conduct electricity
what is the reactivity of acid? acid–base reaction is a chemical reaction that occurs between an acid and a base. It can be used to determine pH.
what is the reactivity of base?
Bases are substances that taste bitter and change the colour of red litmus paper to blue. Bases react with acids to form salts and promote certain chemical reactions (base catalysis).
what is the pH level of acid? pHs less than 7 are acidic
what is the pH level of base? pH of greater than 7 indicates a base.
what is the litmus test of acid?The main use of litmus is to test whether a solution is acidic or basic. Light-blue litmus paper turns red under acidic conditions, and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F).
what is the litmus test of base?The main use of litmus is to test whether a solution is acidic or basic. Light-blue litmus paper turns red under acidic conditions, and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F). Neutral litmus paper is purple.
9. veniger is an acid like many other acids veniger tastes
Answer:
The acid in vinegar is primarily acetic acid, which makes up 4 to 7 percent of table vinegars. Distilled white vinegar, for example, is 5 percent acetic acid and 95 percent water; it has the harsh sourness of acetic acid alone. In other vinegars, that harshness is tamed by other acids.
Explanation:

20. metric unit of volume of acid solution in test tube?
ANSWER;
In addition the "derived quantity", density, will be studied. Make each measurement as accurately as you can, within the limitations of the measuring instrument that you are using. Be sure that the way you record and report this measurement correctly shows the degree of accuracy in the measurement. For example, a meter stick is marked off at intervals of 0.1 of a centimeter, so you can make measurements that are accurate "to the nearest tenth centimeter", or, if you interpolate (estimate between the lines), to the nearest 0.01 or 0.02 cm. If an object that you measure with this meter stick seems to have a length of "exactly" 5 cm, the length should be reported as 5.0 cm (or 5.00 cm if you are interpolating). You should not report the length as 5 cm or 5.000 cm.

Answer:
If you have a carbonyl compound which is not an aldehyde or ketone or carboxylic acid, it could be an ester. One test for esters is the ferric hydroxamate test whereby the ester is converted to a hydroxamic acid (HOHN-C=O) which will give a positive ferric chloride test
Step-by-step explanation:
30. 2. Testing the acid content
Answer:
One of the properties of acids and bases is that they change the color of certain dyes. If these dyes are used to test a substance, the appearance of a particular color can be taken as an indication of the presence of an acid or base in the substance tested.
