Question

The medicine can conditionally be divided into two parts: the active substance and excipients. An active substance is a substance that directly affects the body. Excipients are needed so that the active substance is better absorbed by the body (for example, so that the tablet dissolves only in the stomach, and not earlier). The active substance for a number of
drugs are:
a) KCl - replenishing potassium deficiency,
b) KBr - sedative,
c) KI - replenishing iodine deficiency,

d) CH3COOK - diuretic,
e) KMnO4 - disinfectant.

Determine the mass fraction of potassium in the above drugs (the mass fraction of excipients for all a)-d) preparations should be equal to 95%, for KMnO4 there are no auxiliary substances). Determine the pH of 0.1 M solution of salts mentioned in a) - e) (appropriate constants find in literature).
