Discussion Overview
The discussion revolves around the effects of adding sodium hydroxide (NaOH) to a solution of potassium chromate (K2CrO4) at equilibrium, specifically in the context of Le Chatelier's principle. Participants explore the implications of this addition on the equilibrium position of the reaction involving chromate and dichromate ions.
Discussion Character
- Exploratory
- Debate/contested
- Conceptual clarification
Main Points Raised
- One participant suggests that adding NaOH would not affect the equilibrium because NaOH is a liquid, expressing uncertainty about this claim.
- Another participant questions the effect of NaOH on an acidic solution, implying a potential neutralization reaction.
- There is a suggestion that the reaction will proceed in the forward direction if the acid is neutralized.
- A participant points out the need for a double-headed arrow in the equilibrium equation to properly represent the reaction condition.
- Some participants identify H+ as the acid in the reaction and discuss how the addition of NaOH, a base, would affect the equilibrium by removing protons.
- One participant concludes that the reaction will shift to the left as NaOH takes up protons, although this is not universally agreed upon.
Areas of Agreement / Disagreement
The discussion contains multiple competing views regarding the direction of the equilibrium shift upon the addition of NaOH, with no consensus reached among participants on the final outcome.
Contextual Notes
Participants express uncertainty about the effects of adding NaOH and the implications for the equilibrium position, highlighting a lack of clarity on the definitions and roles of acids and bases in this context.
