All of the above

Answer 1

Nach Nat Cault ci-law) When 3M car's When Na₂.5o4 2- Nace dissolves in water it produces 1 mol Nam and 1 mol ce ion. [Nacij - 3M [ Nat (aa) = Na C2H302 ☺ Nat (aq) + (2 H302 Cars When Na C2H302 dissolves in water it produces 1 mol Nation and 1 mol H₂O2 ioni [ Na C₂ H₂O2] = 3M ** [nati 3M Naz soy Ź 2Na+ (aq) + SO4²- (aqj dissolves in water, it produces 2 mol Nation and 1 mol s04 ion, & [ Naz 504.] = 1.5 M [ Nat (29/] = 2x1.5M 3M Naz Po4 3 Nat (aq) + Poy Cang When Nazpo4 dissolves in water, it 3 mol Nation and 1 mol pogs ion, [ Naz P04 ] = 1M ... Nat Carl 3x1 Ñ .. 3M since all the aqueous solutions have milar concentration of Nat (az). The correct answer will be All of the above (ar) produces CS Scanned with CamScanner
