Converting an Equation to Neutral Form

Click For Summary

Discussion Overview

The discussion revolves around converting an ionic equation into neutral form, specifically focusing on the equation involving thiosulfate and oxygen, with calcium as a counterion for the anions. The scope includes homework-related problem-solving and balancing chemical equations.

Discussion Character

  • Homework-related, Mathematical reasoning

Main Points Raised

  • One participant presents an initial attempt to convert the ionic equation into neutral form by adding calcium to the anions, resulting in a new equation.
  • Another participant suggests that the new equation appears balanced and requests clarification on where the mismatch occurs.
  • A later reply identifies a correction regarding the number of hydroxides, noting that it should be 2Ca(OH)2 instead of 4Ca(OH)2, emphasizing the need to maintain the same number of hydroxides as in the ionic form.
  • Participants express a sense of relief and camaraderie over the initial oversight in balancing the equation.

Areas of Agreement / Disagreement

Participants generally agree on the need to correct the number of hydroxides in the balanced equation, but there is an initial disagreement regarding the balance of the equation before the correction was made.

Contextual Notes

The discussion highlights the importance of maintaining the same number of hydroxides as in the original ionic equation, but does not delve into the specifics of balancing other elements or compounds in detail.

Homework Statement



Hi. I have convert the following equation (which is in ionic form) into neutral form:
4S2O32-+O2+2H2O=2S4O62-+4OH-

The question tells me to use calcium as a counterion for all anions.

The Attempt at a Solution



I basically just added calcium to the anions above, resulting in:
4CaS2O3+O2+2H2O=2CaS4O6+4Ca(OH)2

Unfortunately, when I do a check, the coefficients of each element/compound do not match. Trying to balance it doesn't work.

4CaS2O3+O2+2H2O=2CaS4O6+4Ca(OH)2

Looks balanced to me. Can you show where the mismatch is?
 
Turns out that it's 2Ca(OH)2. It seems obvious in hindsight haha. The number of hydroxides must remain the same as in the ionic form after all.
 
Sorry, I am blind. Sigh.
 
Haha, don't worry about it. I stared at it for a good 15 minutes before I figured it out.
