Given that Ka = 4.3 × 10^-4
At the half equivalence (Stoichiometric) point;
pH = pKa = - log (Ka)
Therefore; pKa = - log (4.3 ×10^-4)
= 3.37
Therefore; the pH at the half-stoichiometric point is 3.37
Answer:
30 protons
Explanation: Each zinc isotope contains 30 protons, 30 massive, positively charged nuclear particles
30 protons, 34 neutrons, and 30 electrons.
Explanation:
Water filtration is the process of removing or reducing the concentration of particulate matter, including suspended particles, parasites, bacteria, algae, viruses, and fungi, as well as other undesirable chemical and biological contaminants from contaminated water to produce safe and clean water for a specific purpose ...
Iodine (I2) is an example of a non-electrolyte. This is a purple-black solid at room temperature. When heated, it turns to a gas (sublimation) producing a beautiful violet cloud. It dissolves readily in many organic solvents, producing violet solutions in most cases and yellow-brown solutions in alcohols. Iodine is not very soluble in water, but produces a slightly yellow solution. No ions are produced when iodine dissolves in any of these solvents.
I believe that it is the first choice, if not the second
