D. None of these​

Answer 1

Answer:

A.White ring at the junction of two fluids

EXTRA INFORMATION :

$\longmapsto$ Acids :

• An acid is a solution that contains replaceable hydrogen atoms.
• Example : Sulfuric Acid [H₂SO₄]

$\longmapsto$ Classification of acid :

$\bigstar$ Strong acid :

• Acid which when dissolved in water produce a large number of $\sf H^{+}$ ions are called strong acid.
• Example : HCL, H₂SO₄.

$\bigstar$ Weak acid :

• Acid which when dissolved in water produce a less number of $\sf H^{+}$ ions are called weak acid.
• Example : CH₃, COOH.

$\longmapsto$ Uses of nitric acid :

• Nitric acid is used as oxidising agent and in the preparation of aquaregia.
• Salts of nitric acid are used in photography and gunpowder for firearms.
