Discussion Overview

The discussion revolves around the solubility of sodium benzoate in hydrochloric acid (HCl), sodium bicarbonate (NaHCO3), and sodium hydroxide (NaOH). Participants explore the chemical behavior of sodium benzoate in these solutions, considering the formation of benzoic acid and the properties of salts in aqueous environments.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that sodium benzoate is soluble in HCl, hypothesizing that benzoic acid is formed along with NaCl.
  • Another participant questions the solubility of sodium benzoate in HCl, noting that HCl is a stronger acid than benzoic acid, which may lead to the formation of insoluble benzoic acid.
  • A third participant agrees with the previous point but expresses uncertainty about the reasoning.
  • Another participant interprets the earlier comments as indicating that sodium benzoate, being a salt, would typically dissolve in aqueous solutions, but they express doubt about this in the context of HCl.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the solubility of sodium benzoate in HCl, with some arguing it is soluble while others contend it may not be due to the formation of benzoic acid. The discussion remains unresolved.

Contextual Notes

Participants reference the behavior of salts in aqueous solutions and the relative strengths of acids, but there is uncertainty regarding the implications of these factors on solubility.

Is Sodium Benzoate soluble in HCl, NaHCO3, and NaOH?As for HCl, I'm guessing benzoic acid is formed along with NaCl so I guess sodium benzoate is soluble in HCl?
I honestly don't even know how to approach this. Thanks for the help in advance.

HCl, NaOH and NaHCO3 are aqueous solutions. What is sodium benzoate? key part 'oate'. What do most salts do in aqueous solutions?

The previous reply would be correct but HCl is a stronger acid than benzoic acid, so in HCl, sodium benzoate would react to form benzoic acid, which is insoluble in acidic aqueous solution. I'm pretty sure this is the right way to think about it, but not 100% sure.
 
You are right, that's what gabriels-horn was hinting at.
 
I think gabriel was implying that since sodium benzoate is a salt, it would dissolve in an aqueous solution. But I don't think that would happen in HCl. Maybe I'm misinterpreting something though.
