Question 3 (4 points) The concentration of hydroxide ions in a solution that has a poH of 6.0 is
a
10-6 M.
Ob
106 M.
Ос
101 M.
Od
10-8 M.

a. 1.0 × 10⁻⁶ M (≈ 10⁻⁶ M)

Explanation:

Step 1: Given data

pOH of the solution: 6.0

Step 2: Calculate the concentration of hydroxide ions ([OH⁻]) in the solution

We will use the definition of pOH.

pOH = -log [OH⁻]

[OH⁻] = antilog -pOH

[OH⁻] = antilog -6.0

[OH⁻] = 1.0 × 10⁻⁶ M

Since [OH⁻] > 10⁻⁷ M, we can conclude that the solution is basic.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
