Discussion Overview

The discussion revolves around identifying which 1 molar salt solution results in the highest pH. Participants explore the relationship between salt composition and pH levels, considering the acidic or basic nature of the salts listed.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Mathematical reasoning

Main Points Raised

  • One participant suggests that NaNO3 would yield the highest pH due to its association with a strong acid, but expresses confusion about determining the pH of salts.
  • Another participant questions whether the inquiry is about the highest or lowest pH, seeking clarification on the terms "strongest acid" and "weakest base."
  • A participant emphasizes that a strong acid corresponds to a low pH, indicating that a high pH would suggest a basic solution.
  • Another participant inquires about which salt is the strongest base, indicating a focus on the basicity of the salts.
  • A suggestion is made to compare the relative strengths of the conjugate acid ions of the salts to determine their basicity.
  • A link to an external resource is provided, which may assist in understanding pH in salt solutions.

Areas of Agreement / Disagreement

Participants do not reach a consensus on which salt results in the highest pH, and there are competing views regarding the definitions of acidity and basicity in the context of the salts discussed.

Contextual Notes

Participants express confusion over terminology related to pH, acidity, and basicity, indicating potential misunderstandings that may affect the discussion. The relationship between the strength of acids and bases and their corresponding pH levels remains unresolved.

Q: A 1 molar solution of which of the the following salts has the highest pH?
A. NaNO3
B. Na2CO3
C. NH4CL
D. NaHSO4
E. Na2SO4

I think its a because NO3 would make a strong acid making more OH but I am coufused totally on how to find pH of salts

Highest pH, or lowest pH? Do you mean which is the strongest acid, or which is the weakest?
 
highest pH

A strong acid has a low pH; for example HCl is around pH of 2. A high pH would indicate a base. A strong acid would not have more OH, so your wording is confusing.
 
which one of them is the strongest base?!
 
A strong base has weak conjugate acid ion.

Compare the relative strength of all the conjugate acid ions

Think along this line

Kelvin
 
this might be useful, although I'm sure you have something similar in your own textbook
