Frequently Encountered Problems and Analysis of Significant Figures Teaching in Analytical Chemistry

School of Chemistry and Molecular Engineering, East China University of Science and Technology, Shanghai 200237, P. R. China

Received Date: 4 February 2018

Analytical chemistry often involves a large amount of experimental data, and the reliability and accuracy of the experimental results are related to whether the original data can be properly recorded and calculated. In this paper, starting from the importance of significant figures, analyzing the frequently encountered problems related to the significant figures in teaching process, and giving some solutions, we try to help students to learn and master the concept of significant figures, rounding off numerical values, rule of operation and data processing.
- Significant figures,
- Data recording,
- Rounding,
- Data processing
