Question

Which of the following aqueous solutions has the highest molar concentrations of Na⁺ (aq)? (Assume each compound is fully dissolved in water.)

Group of answer choices

3.0 M NaCl (sodium chloride)

3.0 M NaC₂H₃O₂ (sodium acetate)

1.5 M Na₂SO₄ (sodium sulfate)

1.0 M Na₃PO₄ (sodium phosphate)

All of the above

Answer 1

3M nad 3 moles 3 m nad means 3m Nach pon I likke of solution. 3M NAC Nad > Nat tel - ccomplete dissociation So 3 Moles of Nach 3 moles Nations Since Imoles of Nad dissociate form Imol Nat, give 3M Nac, H, 02 CH₃COONa :- CH₂ coot Nath Here also imel Chocoonia will dissociale to form one mol nat ion. 3 M $ECH, Coona means Solution So concontation of Nat = 3x1 = 3M 3 mol CH₃Coona per il of 1.5M Na sou Naz Soy Nat S04 +50421 imo Ala2 sou give 2 mol Nation, 1.5 M Nazsoy means 1:5 mol Nazsoy pea k Solution. Sog here, Concentration Nat is a 1.582 - 3M

3 l.om 1.om Na poy 3- + Pou Na, Pou - 3 Nat I mol Na, Poy give 3 mol Nation. Mo Naz pou means IM Na, pou per il solution So concentration of Nat = 1x3 = 3M IM
So Answer is All The Above
