Test for ammonia gas which observation is expected?

Explanation:
Ammonia gas is alkaline, so it turns damp red litmus blue. Bases raise the pH and turn red litmus blue, which is the hallmark observation for a basic gas like ammonia. It wouldn’t make limewater cloudy (that test detects carbon dioxide), and it wouldn’t relight a glowing splint (that test indicates oxygen). So the expected observation is the red litmus turning blue.
