pH is a scale used to measure the acidity or
alkalinity of an aqueous solution. It can be used to calculate the amount of
hydronium ions in the solution. It is expressed as the negative logarithm to
the base 10 of the concentration.

<span>pH= -log [4.5 x 10^-3]</span>
pH = 2.35

Hiii,so the problem is ♀️
Answer:
32, 30 and 41
Explanation:
The problem here is to find the number of:
Protons, neutrons and electrons in Ge²⁺
In this ion,
We must understand that for a net positive charge to remain on an atom, the number of protons must be greater than the number of electrons.
Ge is Germanium with atomic number of 32;
So the number of protons is 32
Since the atom has lost two electrons;
Number of electrons now is 32 - 2 = 30
Number of neutrons is 41 from the periodic table.
