The concentration of hydrogen ion in a sample of soft drink is 3.8 × 10–3M. What is its pH?

Here, AlF3 is an ionic compound in which one formula unit of this has three fluoride ions attached to it. So, in 3 x 1024 number of fluoride ions, number of formula units...

The ions having same number of electrons are called isoelectronic ions. The above order is due to increasing order of effective nuclear charge.

(a) Human muscle fluid 6.83:  pH = 6.83 pH = – log [H+]  6.83 = – log [H+]  [H+] =1.48 × 10–7 M (b) Human stomach fluid, 1.2:  pH =1.2 1.2 = – log [H+]  [H+]...
