AI Thread Summary
In the discussion about which 1 molar salt solution has the highest pH, participants clarify that a high pH indicates a basic solution, while a low pH indicates acidity. The confusion arises from the relationship between acids and their conjugate bases, with emphasis on identifying the strongest base among the options. Na2CO3 is suggested as the likely candidate for the highest pH due to its basic nature, while NaNO3, being neutral, does not contribute to a high pH. The conversation highlights the importance of understanding the strength of conjugate acids and bases when determining pH levels in salt solutions. Overall, the focus is on comparing the basicity of the given salts to ascertain which yields the highest pH.

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 totaly 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
