Compatibility (chemical)

Chemical compatibility is a measure of how stable a substance is when mixed with another substance. If substances mix and do not change they are considered compatible. If substances mix and change or do not mix at all they are considered incompatible. For example, because bleach and ammonia, both commonly used as cleaners are not compatible chemicals, as they react. The recants in this case are dangerous so care must be taken not to allows these chemicals to mix when attempting to use them as cleaners.
