(b) calcium
(c) magnesium
(d) Thorium​

Answer 1

Answer:

A option is correct

Aluminium

Answer 2

Answer:

mordant blue III indicator is used for magnesium detection

Explanation:

Potassium permanganate functions as a signal that indicates the presence of an acidic media when it is brought into contact with an acidic medium.

Potassium permanganate, an oxidising agent, has a colour that may be described as being halfway between a dark violet and a violet.

When used in redox titration, it experiences a colour change at the end point that is plainly noticeable. This is because when it is reduced, it transforms into the brown Mn 2+ ion, which can be seen only after the reduction has taken place (in acidic solutions). Because the indicator's duty is to detect when the reaction has reached its end point, the titration of permanganate does not require a separate indicator in order to function properly.
