The crystal nucleation kinetics measured from the metastable zone width (MSZW) and/or the induction time are vital to the control of the PSD. In this work, the existence of three polyelectrolyte additives (sodium polystyrene sulfonate (SPS), Polyacetic acid (PAA) and sodium carboxymethylcellulose (CMC)) showed varying effects on the MSZW and induction times of NaHCO<sub>3</sub>-Na<sub>2</sub>CO<sub>3</sub>-H<sub>2</sub>O system. SPS lowers the MSZW and induction time while both parameters were increased in the presence of CMC and PAA. The nucleation inhibition effects were observed to be prominent for both PAA and CMC resulting in observed finer PSDs as cooling rate, <em>b</em> increases from 0.5 K/min to 2.65 K/min. The PSD increases with <em>b</em> for both pure and SPS additive, whereas they decrease for both PAA and CMC.</p>}, number={1}, journal={British Journal of Physics Studies}, author={Etroubeka, Caroline Ruth and Asiedu, Daniel and Tegladza, Isaac D.}, year={2022}, month={Dec.}, pages={08–12} }
