Could someone explain how you know that [Ba(OH)2] is equal to [Ba2+] and [OH-] is equal to 2x[Ba(OH)2]? I understand its 2x because there are 2 moles of OH- formed in the reaction, but how are these concentrations determined?
Here is the question for reference:
Calculate the molar concentration of [Ba(OH)2] and the molar concentrations of [Ba2+] and [OH-] and [H3O+] in an aqueous solution that contains 0.43 g of [Ba(OH)2] in 0.100 L of solution.
