Discussion Overview

The discussion revolves around determining the net ionic equation for the reaction between aluminum hydroxide, Al(OH)3, and hydrochloric acid, HCl. Participants are attempting to balance the overall chemical equation and identify the spectator ions involved in the reaction.

Discussion Character

  • Homework-related
  • Debate/contested
  • Mathematical reasoning

Main Points Raised

  • One participant proposes that the net ionic equation is Al3+ + 3OH- + 3H+ = Al3+ + 3H2O, suggesting that Cl- is the only spectator ion.
  • Another participant emphasizes that Al(OH)3 is a solid and should not be dissociated in the net ionic equation.
  • A participant expresses uncertainty about the spectator ions and believes that Cl- is the only one, while also confirming the overall balanced equation.
  • One participant attempts to rewrite the equation as Al(OH)3(s) + 3H+(aq) = 3H2O(l) + Al3+(aq), questioning if this aligns with the instruction regarding Al(OH)3(s).
  • Another participant critiques the previous equations, stating that many of the listed substances do not exist and that the equation is incorrect.

Areas of Agreement / Disagreement

Participants express disagreement regarding the treatment of Al(OH)3 in the reaction, with some insisting it should not be dissociated while others attempt to include it in the net ionic equation. The discussion remains unresolved as participants continue to refine their understanding and proposals.

Contextual Notes

There are limitations regarding the assumptions made about the dissociation of Al(OH)3 and the identification of spectator ions. The discussion also reflects uncertainty in the correct formulation of the net ionic equation.

What is the net ionic equation of Al(OH)3(s)+3HCl(aq)=AlCl3(aq)+3H20

The answer a got was
Cl is the only spectator ion
Al3+ +3OH3- +3H3+ = Al3+ +3H2O

Al3+ +3OH3-

You were told Al(OH)3(s)
 
I was given Al(OH)3(s)+HCl(aq)
then solved and balanced the equation as Al(OH)3(s)+3HCl(aq)=AlCl3(aq)+3H2O(l)
and I know that's correct I just can't figure out the net ionic equation and I'm not entirely sure what the spectator ions are but I'm pretty positive the only ones Cl
 
You are right about spectators, but you are wrong about Al(OH)3 being dissociated. It is given as Al(OH)3(s) for a reason.
 
So now i have it as Al(OH)3(s)+3H3+(aq)=3H2O(l)+Al3-(aq)

thats still not right but is that what you meant by being given Al(OH)3(s)?
 
Equation is so off my eyes hurt from looking, but you are on the right track now. Just half of the substances you listed don't exist.
