Discussion Overview

The discussion centers around the notation NaOH(aq), specifically the meaning of the "(aq)" part, which indicates that sodium hydroxide is in an aqueous solution. Participants explore its significance in chemical equations and experiments.

Discussion Character

  • Conceptual clarification, Technical explanation, Debate/contested

Main Points Raised

  • Some participants propose that "(aq)" means aqueous, indicating that sodium hydroxide is dissolved in water.
  • Others question the necessity of the notation and its relevance to specific experiments.
  • One participant mentions that aqueous solutions have important implications depending on the experiment being conducted.
  • Another participant provides an example of hydrochloric acid, noting that it is only considered an acid when dissolved in water.
  • There is a discussion about balancing chemical equations involving NaOH(aq) and iron(III) nitrate, with a focus on net ionic equations.
  • One participant challenges the formatting of "(aq)", suggesting it should not be bold or italicized, leading to a clarification about the visual representation in sources.

Areas of Agreement / Disagreement

Participants generally agree on the meaning of "(aq)" as indicating an aqueous solution, but there is some contention regarding its formatting and the implications of using it in different contexts.

Contextual Notes

Participants express varying levels of understanding regarding the importance of aqueous solutions in chemical reactions, and there are unresolved questions about the formatting of chemical notation in different sources.

What is this bolded part?

NaOH(aq)

Mind you, the bolded part is subscripted. I've seen that once before but don't remember reading anything about it.
 
Physics news on Phys.org
It means aqueous.
 
Is it used for anything or is it simply there?

:smile: It indicates that the Sodium Hydroxide is dissolved in water.
 
What's that got to do with what I'm doing though?:bugeye:

Nyah, I figured that'd be at least a slightly amusing question.:smile:
 
it has important implications, depends on which experiment your doing.
 
Aqueous solutions are solutions in which the solvent is water.

An example is HCl. Most people refer to this as hydrochloric acid. But in reality it is only an acid if the gases are dissolved in water.

I'm balancing an equation-- NaOH(aq) + Fe(NO3)3(aq) -->
 
yeah, you can write out any important net ionic equations. The NaOH will actually be dissolved to Na+ and OH- right (and the same for iron II nitrate); except you might want to see if you've got any precipitates or anything else for a net ionic equations.

Wrong. It should be the same size as rest of the text, and not bold nor italic.Borek

What do you mean, wrong? How could I be wrong by stating what I see right in front of me? O_o

And it isn't bold or italic...

I didn't mean you are wrong. I mean (aq) should be the same size as the rest of the text - if it is subscripted, book (or any other source you are looking at) uses it improperly.Borek
