Discussion Overview

The discussion revolves around the comparison of pH levels between vinegar (acetic acid) and sulfuric acid solutions, as well as related questions about solvent miscibility and the properties of hydrogen peroxide as an oxidizing agent. The scope includes theoretical chemistry and conceptual understanding of acid strength and solvent interactions.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions how to calculate the pH of a 5% sulfuric acid solution and compares it to a 5% acetic acid solution, noting that vinegar is a weak acid.
  • Another participant expresses frustration over the lack of responses to the chemistry questions posed, emphasizing that it is not a homework inquiry but rather a personal curiosity.
  • A participant references an external discussion that may provide additional insights into the topic of pH comparison.

Areas of Agreement / Disagreement

Participants do not appear to reach a consensus on the pH comparison between vinegar and sulfuric acid, nor do they resolve the other questions raised in the thread. Multiple competing views and uncertainties remain regarding the topics discussed.

Contextual Notes

The discussion lacks detailed calculations or definitions that could clarify the assumptions behind the pH comparison. The relationship between solvent miscibility and the behavior of water traces in a mixture is also not fully explored.

Hi there, I was wondering if anyone could help me with 3 questions:

1) Without pH papers, how do you calculate the pH of a 5% H2SO4 (sulfuric acid) solution?
I know vinegar is a weak acid, but would a 5% acetic acid have the same pH of a %5 H2So4 solution?

2) If a non-polar solvent such as Hexane is miscible with Ethanol, does that mean that they mix completely? If so, would the water traces from the alcohol stay at the bottom below the Hexane layer?

3) H202 (Hydrogen peroxide) is an oxidizing agent just like Permanganate. I need to replace the later, is it possible to dilute or concentrate Peroxide in order to make it work like Permanganate?
Besides one begin stronger than the other, what other differences are there between these oxidizing agents? :confused:

Thanks :biggrin:

and it's not homework, just something I've always wondered
 
Thank you
