In the standard Ziegler-Natta catalyst mixture used for HDPE synthesis, what is the oxidation state — Polymers Chemistry Question
Question
In the standard Ziegler-Natta catalyst mixture $[(C_2H_5)_3Al + TiCl_4]$ used for HDPE synthesis, what is the oxidation state of Titanium ($Ti$) in the transition metal halide component?
Answer: 4
💡 Solution & Explanation
The transition metal halide is Titanium tetrachloride ($TiCl_4$). Chlorine has an oxidation state of $-1$. Therefore, to balance the charge of the neutral molecule, Titanium must have an oxidation state of $+4$.
