From experimental data, a plot of absorbance (in arbitrary units, a.u.) at a wavelength of 630 nm (on the y-axis) was plotted against the concentration (in mg/L) of Cu2+ (on the x-axis) in known solutions and a linear relationship was found with an equation of y = 7.22x+0.05. If an unknown solution had an absorbance of 1.20 a.u. at a wavelength of 630 nm, what is its concentration of Cu2+?
A student determined the chloride content of a commercial salt by using the Mohr method. A 0.7725 -g sample of the salt was dissolved in distilled water and diluted to a final volume of 250. mL. A 25.-mL aliquot of the analyte solution was then titrated against a standard 0.0347 M AgNO3(aq) solution to the chromate end-point. A blank-corrected volume of 25.96 mL was recorded. Calculate the percent chloride in the sample.
