Question

Which net ionic equation describes the reaction between NaOH( aq) and HCl( aq)?

Na +( aq) + OH –( aq) → NaOH( aq)
OH –( aq) + H +( aq) → H2O( l)
Na +( aq) + Cl –( aq) → NaCl( s)
OH –( aq) + H +( aq) → H2O( l) + Na +( aq) + Cl –( aq)

Answer 1

OH- + H+ H2O

Step-by-step explanation:

A P E X

Answer 2

OH–( aq) + H+( aq) → H2O( l)

Step-by-step explanation:

Step 1: Data given

Hydrochloric acid = HCl

⇒ dissociates in H+ and Cl-

Sodium hydroxide = NaOH

⇒ dissociates in Na+ and OH-

Step 2: The equation

NaOH(aq) + HCl(aq) → Na+ + OH- + H+ +Cl-

Na+(aq) + OH-(aq) + H+(aq) + Cl-(aq) = Na+ (aq) + Cl-(aq) + H20(l)

After canceling the spectators ion (= ions that do not take place in a chemical equation, Na+ and Cl-)

OH–( aq) + H+( aq) → H2O( l)
