In this section the results of Cuprous Chloride(WSDTY) the metastability experiments and equilibrium constants are presented. To determine the unknown variables in Equation (4) and ensuring independence of concentration, average and weighted-average values for m, and y-int are calculated. The calculation uses the number of data points per concentration divided by the total number of data points as the weights.The nucleation order and nucleation rate constants are almost all within 1 of a weighted average. Cooling rate has a dominant influence on MSZW, whereas concentration has a minor influence on MSZW. It is likely that HCl acts as a crystallization inhibitor since higher ln(MSZW) are found at lower HCL concentrations.

The relation between MSZW (dependent variable) and concentration (independent variable) is plotted, for various cooling rates. Linear fits are applied for 0.25 K/s and 0.5 K/s. For the 0.5 K/s dataset, point is probably an outlier, thus two linear fits are applied for 0.5 K/s, one fit including the outlier and the other without. The linear fit without the outlier has a stronger linear correlation. Further experimentation is required to determine if the point at is an outlier.

MSZW decreases with concentration and MSZW increases with faster cooling rates, which agrees well with previous experimental results. This is likely caused by higher cooling rates, producing a lower temperature before observing the first crystal, thus lowering Tmet and increasing MSZW. If the temperature is decreasing too rapidly, Tmet may be passed because the solution was unable to crystallize at the maximum value of Tmet due to the rapid cooling rate. When the cooling rate is slower, the solution has time to begin crystallizing at the maximum value of Tmet.
