Witrynapolyprotic (diprotic, triprotic) acids can donate more than one proton to another molecule and have more than one equivalence point. In our case we have potassium hydrogen … Witryna2 lut 2024 · Acid-base indicators are either weak organic acids or weak organic bases. The equilibrium in a solution of the acid-base indicator methyl orange, a weak acid, can be represented by an equation in which we use HIn as a simple representation for the complex methyl orange molecule: HIn ( aq) ⏟ red + H 2O ( l) ⇌ H 3O + ( aq) + In − ( …

WitrynaNo, the ratio between Ba (OH)2 and HCl is the only important that is one here. 1 mole of Ba (OH)2 requires 2 moles of HCl to neutralise it. In this video there are 0.000422 moles of Ba (OH)2, so that requires 0.000844 moles of HCl in order to neutralise it, agreed?
