Table 2

Binodal curve coefficients of (1) for PEG 6000 + sodium succinate + water at various temperatures.

Temperature,; K	𝐴	𝐵	𝐶	𝐷	𝑅^2	AARD* (%)	SD**
298.15	247.48	−111.43	14.98	−0.09	0.9823	4.07	0.55

∗Average arithmetic relative deviation (AARD) = {∑^𝑁_𝑖(‖Expt−Cal/Expt‖)/𝑁}×100.
**Standard deviation (SD) = {∑^𝑁_𝑖(Expt−Cal)²/𝑁}^1/2.
