Discussion Overview

The discussion revolves around the solubility of various ionic compounds in water at room temperature, specifically Na2CO3, Ag2CO3, K2SO4, Mg(OH)2, and ZnS. Participants are reviewing and verifying answers related to a homework question.

Discussion Character

  • Homework-related

Main Points Raised

  • One participant states that Na2CO3 is insoluble, while another asserts that sodium carbonate is soluble.
  • Ag2CO3 is indicated as insoluble by the initial poster, with no further comments challenging this.
  • K2SO4 is noted as soluble by the initial poster, and this claim appears to be accepted without dispute.
  • Mg(OH)2 is listed as insoluble, with no further discussion on this point.
  • ZnS is also marked as insoluble, with no additional commentary provided.

Areas of Agreement / Disagreement

There is disagreement regarding the solubility of Na2CO3, with some participants asserting it is soluble while others maintain it is insoluble. The other compounds' solubility statuses remain largely unchallenged.

Contextual Notes

Participants do not provide detailed justifications or references for their claims, and the discussion lacks comprehensive exploration of the solubility rules that might apply to these compounds.

Who May Find This Useful
