question 10 of 10
how does the oxidation state of li change in the following reaction?
li(s) + naoh(aq) → lioh(aq) + na(s)

a. it does not change.

b. it goes from +1 to +2.

c. it goes from 0 to +1.

d. it goes from 0 to -1.

Explanation:

Step1: Find Li's initial oxidation state

Li is in elemental form (Li(s)), so oxidation state = 0.

Step2: Find Li's final oxidation state

In LiOH, Li is a Group 1 metal, so oxidation state = +1.

Step3: Determine the change

Li goes from 0 to +1.

Answer:

C. It goes from 0 to +1.
