During electroplating of silver on a copper spoon, the electrolyte used is:
A. Sodium chloride solution
B. Copper sulfate solution
C. Silver nitrate solution
D. Copper nitrate solution
Answer: Option C
Solution (By JKExamLibrary)
In electroplating, the electrolyte must contain the ions of the metal to be deposited. To plate silver, a solution of a silver salt, such as silver nitrate (AgNO₃) or silver cyanide, is used. The anode is pure silver, and the cathode is the copper spoon to be plated.
Explanation:
Half-life (T₁/₂) is the time taken for the number of radioactive nuclei (or activity) to decrease to half of its original value. It's a constant characteristic of each radioisotope. For example, C-14 half-life is 5730 years.
Explanation:
Sodium bicarbonate (NaHCO₃) neutralizes excess stomach acid (HCl) and provides relief from acidity. It is a mild base. NaOH is too strong and corrosive. NaCl is table salt; CaSO₄ is used in plaster of Paris.
Explanation:
Liquefied Petroleum Gas (LPG) primarily consists of butane (C₄H₁₀) and isobutane, with some propane. For domestic use, it is often a mix of butane and propane. Methane is the main component of CNG and natural gas, which require different storage pressures and infrastructure.
