Question

(HELP PLEASE)

Howard is working with a cleaning solution that contains sodium hydroxide. Although he is using gloves, when he pours the solution to dilute it for cleaning use, he spills a bit on his arm. His arm feels slimy to the touch and now has a burn mark. What is the chemical route of entry?

Inhalation


Ingestion


Injection


Absorption​

Answer 1

D.Absorption

Step-by-step explanation:

His skin soaked up the cleaning solution, like how a sponge soaks up moisture. In order to double check, lets see what the other answers would be.

Inhalation

Howard didn't inhale the solution

Ingestion

Howard didn't consume the cleaning agent.

Injection

Injection is an instance of injecting or being injected.

Howard was not injected by a syringe/needle.

So your answer is D. Absorption
