© 2020, Chiang Mai University. All rights reserved. A low-cost stopped-flow spectrophotometric system was fabricated in the laboratory for a kinetic study on the reaction of molybdenum blue with arsenate. The influence of the concentration of the reagents on the rate of reaction has been studied. Ar...
