Question

question 5
the ph of a solution is the negative logarithm of which of the following?
the concentration of hydroxide ions in the solution
the concentration of hydrogen (hydronium) ions in the solution
the concentration of potassium ions in the solution
the kw of the solution

question 6
a solution with a ph of 10 can be correctly described as which of the following?
acidic
basic
neutral
amphoteric

question 7
what is the ph of a neutral solution?
less than 7
more than 7
7
0

Explanation:

For Question 5: The pH formula is \(pH =-\log[H^{+}]\) (where \([H^{+}]\) is the concentration of hydrogen (hydronium) ions).
For Question 6: Solutions with \(pH>7\) are basic. Since \(pH = 10>7\), it is basic.
For Question 7: By definition, a neutral solution has \(pH = 7\).

Answer:

Question 5: the concentration of hydrogen (hydronium) ions in the solution
Question 6: Basic
Question 7: 7
