Iron (II) iodide solution will contain the highest concentration of iodide ions. Option D is the right answer.
Explanation:
Reference table F is used to check the solubility of the metal compounds formed. It tells if the compound is soluble or insoluble in water.
From the table, it is seen that Mercury, silver and lead form insoluble complex with iodide ions. This means that they have low concentration of dissolved iodide ions. These three metals lead, silver and mercury are given as exception in the table F.
Thus iron(II) iodide will have highest concentration of iodide ions when dissolved in water.
7.6% KCl I had the same problem on my semester exam for summer school
Answer is: less acetic acid to neutralize it.
Balanced chemical reaction of sodium bicarbonate solution and acetic acid: NaHCO₃(aq) + CH₃COOH(aq) → CH₃COONa(aq) + H₂O(l) + CO₂(g).
According to chemical reaction: n(NaHCO₃) : n(CH₃COOH) = 1 : 1.
Stronger solution of sodium bicarbonate (NaHCO₃), more acetic acid (CH₃COOH) is neeed for neutralization.
Answer: False
Explanation: Electrolyte are good conductors of electricity because they contain ions which are able to move about
Answer:
Mineral dusts are solid particles, that may become airborne depending upon their origin and the surrounding physical conditions. Lead is potential poison. It is obtained from the earth crust. The lead poisoning is a popular occupational hazard. The lead in air, when taken by the human body through respiration is responsible to cause anemia, weakness and kidney and brain damage, labored breathing and lung diseases.
