Advantages and disadvantages of traditional acid-base titration and handheld technology

Advantages and disadvantages are mainly composed of data collector and sensor. The physical quantities of chemistry are identified by sensors, and then the physical quantities are converted into electrical signals, and then the electrical signals are converted into numbers by data collectors and software, which are presented on the computer screen in a combination of numbers and graphics. It is convenient, real-time, accurate, intuitive and comprehensive, which can improve the level of high school chemistry experiments and solve the difficulties of traditional experiments.
