which of these substances would have the lowest ph? course hero

How do you order these substances from highest to lowest pH?

2) If an element in group 2 of the periodic table formed a compound with an element in group 7 of the periodic table, the compound formed is likely to: A conduct electricity in the solid state. B have a low boiling point. C dissolve in non ‑ polar solvents. D be a crystalline solid.

Why is the pH of NH3 higher than HBrO?

Nov 13, 2016 · Sr(OH)2(aq) > NaOH(aq) > NH3(aq) > HBrO(aq) > HBr(aq) Here's what we should know: The stronger the base, the higher the pH, since it dissociates more in solution than weaker bases, thus making it more basic and raising the pH. The stronger the acid, the lower the pH, since it dissociates more in solution than weaker acids, thus making it more acidic and lowering the …

How does the strength of a base affect the pH?

Practice Test Question #4: Which of these substances has the lowest pH?

How to determine the pH of a solution?

Here's what we should know: 1 The stronger the base, the higher the pH, since it dissociates more in solution than weaker bases, thus making it more basic and raising the pH. 2 The stronger the acid, the lower the pH, since it dissociates more in solution than weaker acids, thus making it more acidic and lowering the pH.

What does a stronger base do to the pH?

The stronger the base, the higher the pH, since it dissociates more in solution than weaker bases, thus making it more basic and raising the pH. The stronger the acid, the lower the pH, since it dissociates more in solution than weaker acids, thus making it more acidic and lowering the pH. Now let's figure out where the acids and bases fall on ...

Is HBrO a weak acid?

We now know that HBrO is a weak acid, so it must dissociate less than HBr, meaning that it decreases the pH by less from about 7. That means the pH of HBrO(aq) > pH of HBr(aq). Now we have: Sr(OH)2(aq) > NaOH(aq) >? > HBrO(aq) > HBr(aq) Since NH3 is a weak base, it increases the pH by less than NaOH, but since it increases ...

Is Sr(OH)2 as concentrated as NaOH?

That means Sr(OH)2 is twice as concentrated with OH− as NaOH is.

Does NH3 increase pH?

Since NH3 is a weak base, it increases the pH by less than NaOH, but since it increases the pH and HBrO decreases the pH, it means that in general the same concentration of both implies that the pH is higher for NH3(aq) than HBrO(aq). Therefore, our result is:

What is pH based on?

a. pH is based on the [H3O+] in solution.

What is the pH of a neutral solution?

c. If pH = 7.0 then the solution is neutral.
