Answer 1

Answer:

the answer is number d) I think

hope my answer is right

Answer 2

The correct answer is option (d) 0.1 M HCl saturated with Hg, Cl.

Explanation:

• The thin glass bulb in glass electrode is filled with 0.1 M HCl saturated with Hg, Cl.
• The glass electrode consists of a glass tube with a thin glass bulb at the tip.
• A glass electrode (sensing electrode) consists of a thin glass bulb (special quality) containing a fixed concentration of HCl solution, into which a Ag-AgCl wire is inserted, serving as the electrode with a fixed voltage.
• Glass electrodes are commonly used for pH measurements.
