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.
A Porshe can do it in 5 seconds, but a cricket ball does it 10,000 times faster. The average force on the ball is 8,800 N, enough to lift a mass of 880 kg off the ground. The peak force on the ball is about double that, enough to lift a 1.76 tonne car off the ground.
