Need help with BC please Practitioners of homeopathic medici

Practitioners of homeopathic medicine believe that good health can be restored by administering a small amount of a harmful S substance that stimulates the body\'s natural healing processes. The remedy is typically prepared by serially diluting an animal or plant i extract. In a so-called 30X dilution, the active substance is diluted 10-fold, 30 times in succession If the substance is initially present at a concentration of 1 M, what is its concentration after a 30 times dilution? A typical homeopathic dose is a few drops. How many molecules of the active substance would be present in 1 mL? When confronted with the results of an exercise such as the one in part (b), proponents of homeopathy claim that a molecule can leave an imprint, or memory of itself, on the surrounding water molecules. What information presented in this chapter might be used to support this claim? To refute it?

Solution

(5)

(a)Stock: 1 M

Dilution factor = 1/10^30

Concentration of the product = stock x dilution factor

= 1 x 10^-30 M

(b) 1 M solution contains 6.022140857 × 10^23 molecules/Litre

Or 6.022140857 × 10^20 molecules/mL

1 x 10^-30 M solution -----------> 6.022140857 × 10^-10 molecules/mL

Means the solution doesn’t contain any substance at all!

(c) Higher dilutions make the active substance sparsely available or not at all.

(d) Water has no memory, this method of Homeopathy is a pseudoscience.
