The most dominant male birds in the area is the first to break the night-time silence with their call, followed by the second most dominant. Cockerels (like those abve) call in the morning according to the social hierarchy of the flock, with the most dominant male crowing first, according to a study.
A low-precision gravimetric titration can achieve 10,000.the same. reproducibility as a titration with a 50 mL volumetric buret. It requires less reagent quantities, it is faster and less. complicated titration for the students and the teacher, and the equipment. is far less expensive.
At this point the number of equivalents of A added to the unknown equals the number of equivalents of B originally present in the unknown. Volumetric methods have the potential for a precision of up to 0.1%. For volumetric methods to be useful, the reaction must reach 99%+ completion in a short period of time.
