Answer:

1. Using Litmus papers. Litmus paper will turn blue if solution is acidic or it will turn blue if it is basic. ... If pH is below 7 or reddish then the given solution is acidic and if pH is higher than 7 or bluish then the solution is basic.

Answer:

Explanation:

One: You could mix a small sample of it with a reactive metal. Underline small. You should see gas bubbles being given up. Usually the bubbles are hydrogen.

Example : K + HCl ===> KCl + H2

Two: You could use an indicator to watch it turn color as it goes from acidic to neutral. Litmus will go from red to blue under these conditions.

Three: Those are the two safest ways. If you knew the acid was dilute, you could put a small (underline small again) amount on your tongue. If it tastes like orange juice, it is likely an acid. This is a test every textbook mentions. You should never do it under any circumstances.

Describe an experiment to show that water contains hydrogen and oxygen only​
kondaur [170]

Answer:

Electrolysis

Explanation:

The electrolysis of water is one such experiment that shows that water is made up of hydrogen and oxygen atoms only in the ratio of 2 to 1.

In the electrolysis of water, electricity is passed through acidified water to cause it to decompose.

The electrolysis of water is also known as the electrolysis of dilute tetraoxosulphate  (VI) acid.

At the cathode, H⁺ ions are discharged and hydrogen gas is liberated:

               2H⁺       +     2e⁻     →        H₂

At the anode, both the sulfate ion and hydroxyl ions migrate to this electrode. Only the OH⁻ is selected for preferential discharge due to its lower position in that activity series.

         4OH⁻  →   2H₂O    +    O₂     +     4e⁻

Oxygen gas is produced at the anode.

This electrolysis demonstrates the volumetric composition of water that is, 2 volumes of hydrogen at the cathode and 1 volume of oxygen at the anode.

The polymerization of amino acids produces:
Delicious77 [7]

Answer:

Proteins

Explanation:

Polymerization, in chemistry, is the chemical combination of monomeric units to form a polymer. Polymers are large molecules made up of smaller units called monomers. Amino acids are the monomeric units of proteins i.e. A protein is made up of of many amino acids joined together.

Therefore, the chemical combination of amino acids will form a peptide bond between the carbon atom of the acid group and nitrogen atom of the amine group in the structure of the amino acids. This is done by the loss of a water molecule. The continuous repetition of this polymerization process will form a chain called polypeptide, which is the PROTEIN.
