  • How do I calculate the molarity of 7. 24 * 10^2 mL of solution . . .
    How do I calculate the molarity of 7 24 * 10^2 mL of solution containing 22 4 g of potassium iodide?
  • What occurs to magnesium nitrate, and potassium iodide in aqueous . . .
    Neither magnesium nitrate nor potassium iodide are insoluble in aqueous solution they dissolve to form their aquated ions And dissolution of these salts in water would simply give the aquated ions 2KNO_3(aq) + MgI_2(aq) rarr 2KI(aq)+Mg(NO_3)_2(aq) All nitrate salts are soluble, and most common magnesium salts are soluble
  • Question #ebceb - Socratic
    The amount of potassium iodide or iodate required is extrtemely small, however To make 1 tonne (1000 kg) of iodised salt, you only need about 63 g of potassium iodide But it should be noted that the element iodine is not used in the preparation of iodised salt, nor is it found in the finished product
  • Question #7ba31 - Socratic
    Test the conductivity of the solution You can use a multimeter to measure the conductivity, and the higher the conductivity the more saturated the solution is Since NH_4Cl is an electrolyte, that means it dissociates into its constituent ions (NH_4^(+) and Cl^(-)) when dissolved in water Since it dissolves into its ions, that means the water is able to conduct electricity because the ions
  • What is wrong with saying that solid potassium chloride is composed of . . .
    It is incorrect because potassium and chlorine do not react to form molecules There is no such thing as a "KCl molecule" Potassium has a valence of 1, and chlorine is significantly more electronegative than potassium Therefore, the reaction between the two proceeds by potassium losing its outer valence electron to form a positive ion, and chlorine gaining the electron to complete its outer
  • Site Map - Mole Ratios Questions and Videos | Socratic
    What molar quantity of #PbI_2# can be formed from a #5 85*mol# quantity of #"potassium iodide"#? What is the molecular mass of #NH_3#? Question #9caeb How are mole ratios derived from balance equations? How much alumina is formed if #4 2*mol# of aluminum is oxidized? Question #54603
  • How many valence electrons are transferred from the calcium . . . - Socratic
    2 valence electrons Calcium iodide (CaI_2) is an ionic bond, which means that electrons are transferred In order for Ca to become the ion Ca^(2+), the calcium atom must lose 2 electrons (Electrons have a negative charge, so when an atom loses 2 electrons, its ion becomes more positive ) In order for I to become the ion I^(1-), the iodine atom must gain 1 electron (When an atom gains an
  • Potassium ions (K^+#) have a positive charge. What happens . . . - Socratic
    Well, usually they have caused a reduction in another reagent We drop a (small!) chunk of potassium in water, and some of the water is reduced to dihydrogen And we can represent by a pair of redox rxns: K(s) rarr K^(+) + e^-; "oxidation" H_2O(l) + e^(-) rarr 1 2H_2 + HO^-; "reduction" Overall, K(s) + H_2O(l) rarr KOH(aq) + 1 2H_2(g) In a teaching lab, it is better to use lithium or sodium to
  • Question #c5f79 - Socratic
    Hydrogen iodide Propyne gives a mixture formed by the addition of one or two moles of
  • If the concentration of potassium chloride is low during electrolysis . . .
    I think the question just answered it self, since it says that the concentration of KCl is low Hence most of the chlorine if not all would have been used up in the reaction C = m v And where the oxygen is coming from, perhaps water is used as a solvent or it is contained in the solution
