Which of the following reagents can cause serious eye damage? Multiple answers: You can select more than one option
A potassium tert-butoxide B sodium methoxide C 10% potassium hydroxide solution
The pH of a eye drop is 7.5. Anything having pH above 7.5 and below 7.5 can cause eye irritation.
Now the given compounds are strong bases and having pH more than 7.5. So all of the compounds will cause eye damage
