WebOct 13, 2016 · This is where the solid–solid reactions of barium hydroxide with ammonium salts are useful. Here I describe two. The thiocyanate reaction works much faster and is my preferred method, but the chloride salt is more widely stocked and thermodynamic data for it is easier to find. WebA precipitation reaction is when two aqueous ionic compounds form a new ionic compound that is not soluble in water. One example is the reaction between lead (II) nitrate and potassium iodide. Both compounds are white …
