which of the following solutions contains the greatest numberof ions? Assume complete solubility for all salts. Include theformula for the compound named in your answer: a. One mole of potassim chloride dissolved in 1.0 L ofwater b. One mole of sodium phosphate dissolved in 1.0 L ofwater c. One mole of iron (II) nitrate dissolved in 1.0 L ofwater d. One mole of sodium hydroxide dissolved in 1.0 L ofwater. which of the following solutions contains the greatest numberof ions? Assume complete solubility for all salts. Include theformula for the compound named in your answer: a. One mole of potassim chloride dissolved in 1.0 L ofwater b. One mole of sodium phosphate dissolved in 1.0 L ofwater c. One mole of iron (II) nitrate dissolved in 1.0 L ofwater d. One mole of sodium hydroxide dissolved in 1.0 L ofwater.Explanation / Answer
First, write down all the formula of the compound first Potassium chloride - KCl Sodium phosphate - Na3PO4 Iron(II) nitrate - Fe(NO3)2 Sodium hydroxide - NaOH Then, determine how many ions there are KCl - 2 ions (1 K+ and 1 Cl-) Na3PO4 - 4 ions (3 Na+ and 1PO43-) Fe(NO3)2 - 3 ions (1 Fe2+ and 2NO3-) NaOH - 2 ions (1 Na+ and 1 OH-) The answer is (b) One mole of sodium phosphate dissolved in 1.0 Lof water It contains 4 mol of ions (3 Na+ and 1PO43-) Hope this helps!
