Using the method of successive approximations, what is [H3O+] in 0.00500 M CH2ClCOOH(aq) (Ka=1.4×10−3) and how many iterations (n) are needed to validate that a constant value had been obtained to two significant figures? Express [H3O+] using two significant figures, followed by a comma and the number of iterations as an integer.
If we assume that x is very small compared to 0.00250, the first iteration gives x=(0.00250×4.5×10−4)1/2=0.00106. Even though the assumption is not valid, it seems likely that [HNO2] is closer to (0.00250−0.00106)M than to 0.00250 M. Substitute the new value into the original equation to obtain the second iteration, x20.00250−0.00106=4.5×10−4 and then x=8.04×10−4. Now, we can restrict x to the following range: 8.04×10−4<x<1.06×10−3 Use the new value of x to write that [HNO2]=(0.00250−0.000804)M and solve the equation once again for...
