However, this reaction generates ammonia gas, which may have to be absorbed in the acid wash.

Six fire units and a hazardous chemicals unit were called to the chemical plant to deal with the leak of the ammonia gas.

For instance, ammonia gas, which is alkaline, colors the red litmus paper blue.

However, the next step exposed the paper to an ammonia gas.

Every thing was built on a scale too small and the air contained thick traces of ammonia gas, anyway.

Hot ammonia gas is also present to fluidize the bed and inhibit deammonization.

Unsealing such containers can lead to a burst of ammonia gas.

Chaulnes proposed a way to recover from suffocation through the administration of ammonia gas in various forms.

The experiment consists of introducing water through an inlet to a container filled with ammonia gas.

This results in the liberation of ammonia gas and an acid.
