Draw a series of titration curves for the titration of a strong base with a strong acid where the concentration of the acid is 10-1, 10-2, and 10-3 mol dm3 respectively. give details why the option of indicators is limited at different acid concentrations.
This is a fact that Bromine(Br) is larger than chlorine(Cl) but indication of equilibrium constant suggests that a bromo substituent has a less preference for the equatorial position than chloro substituent? Explain it briefly?
Chemical Kinetics - Predict the rate law of a reaction based on the mechanism of the reaction - What is the overall reaction and Predict the rate law based on the mechanism.
