Gelatinization of Acacia mucilage occurs when it is combined with which element?

Explanation:
Gelatinization of Acacia mucilage happens when multivalent metal ions bridge the gum’s polymer chains. Acacia mucilage contains carboxylate groups that can bind metal ions; ferric ions (Fe3+) are highly effective at linking multiple polymer chains, creating a cross‑linked network that traps water and forms a gel. This stronger cross-linking with Fe3+ makes gelatinization occur readily, more so than with the other ions listed, which interact less strongly or with lower charge.
