Question

You measure 7 calibration standards for iodide in sea ice and determine the following:

Concentration (ppb)	Method Response
5	200
15	550
30	1210
45	1742
60	2500
75	3150
100	4000

a) Report the correlation coefficient and equation for this line (assume rectilinear).

b) Solve for the concentration of iodide indicated by a signal of 840.

c)The iodide method also returns a signal from bromide with a KA,I of 1x10-3. Explain what experimental technique you would need to use to account for the bromide signal in your samples.
