What Is The Formula Equation For Barium Chloride + Sodium Hydroxide?
Barium’s ionic charge is 2+ and chlorine’s is 1-, meaning you need 2 chlorine ions for each barium ion in barium chloride. The polyatomic ion hydroxide has a 1- charge, and sodium’s is 1+, so you need no subscripts for sodium hydroxide. The reaction between BaCl2 and NaOH is a double replacement reaction because there are two polyatomic compounds, both with metal ions, reacting. The barium and sodium ions will literally swap places with each other to form barium hydroxide and sodium chloride.
