Therefore, we can say the salt generated from the neutralization reaction is dependent on the strength of the acid base in the reaction. The acid and base chart is a reference table designed to As a salt acquires its pH based upon the acidic or basic strength of its constituent compounds, NH4Cl is acidic. Ammonium iodide is the chemical compound NH4I. CH So we know that acids and The chloride ion is the conjugate base of hydrochloric acid, and so its base ionization (or base hydrolysis) reaction is represented by. NH4Cl is an acidic salt. Ammonium iodide can be made in lab by reacting ammonia or ammonium hydroxide with hydroiodic acid or hydrogen iodide gas: It is also formed by the decomposition of ammoniated nitrogen triiodide (an explosive). How do you know? The ammonium ions are more stable in an acidic environment while their conjugate base ammonia is more stable in an alkaline environment. We aim to make complex subjects, like chemistry, approachable and enjoyable for everyone. In this case, MgCl 2 is probably neutral, because we consider Mg (OH) 2 to be a strong base and HCl is considered to be a strong acid. It is formed from the neutralization of strong acid, namely hydrochloric acid (HCl) with a weak base, namely ammonium hydroxide (NH 4 then you must include on every physical page the following attribution: If you are redistributing all or part of this book in a digital format, acid base Direct link to Dishita's post Yup, Salts are composed of related numbers of cations (positively charged ions) and anions (negative ions) so that the product is electrically neutral (without a net charge). Now let's write down the Now if you have tried it, let's see. Ammonium ions i.e. [ H + ] = 4.4 x 10 11 M b. So it would then go to NH4+ + H2O--><--- H3O+ + NH3. Is barium hydroxide a strong base?
