Lastly, looking at the Lewis concept, the ammonium ion does not have any lone pair of electrons at its central atom and hence, it has the tendency to accept protons donated by other molecules. ions involve bonds between a central Al atom and the O atoms of the six water molecules. In the reaction, NH4+ serves as a acid and I- as a base. could someone please redirect me to the other videos which explain how and why the salts take on their dominant parent's properties.

This book uses the How many minutes does it take to drive 23 miles? how salt can be acidic and basic in nature. NH4+ also called ammonium ion is the conjugate acid of ammonia and chloride ion(Cl) is a conjugate base of hydrogen chloride. Strong acids are those that readily and completely ionize in an aqueous solution. Sodium acetate, CHCOONa. An aqueous solution of NH4Cl has an acidic property with a pH value range from 4.5 to 6. Is a solution of the salt KNO3 acidic, basic, or neutral? (problem: NH4OH is not an exsisting compound, most of it will react with the strong acid H+ and the remainig will be fully ionized into NH4+), (problem solved: not using NH4OH as it is annon-exsisting compound). So over here we have a weak acid but a strong base. Now the next step is to find out what is the nature of acid and base. When NH4Cl goes through the hydrolysis process, it split into two ions (NH4+ + Cl). It is used as an ingredient in cough medicine. Is a solution with OH- = 1 x 10-6 M acidic, basic, or neutral? According to the Arrhenius concept, the compound is said to be base when it produces OH ion through ionization or through dissociation in water. Is the pH of blood acidic, basic, or neutral? So what I mean is that when a strong acid and a strong base react, the salt that gets formed is neutral because they both have equally neutralized each other's effect. reacting with a strong base, it also takes the nature of the strong parent. Direct link to pipipipipikatchu's post should we always add wate, Posted 3 years ago. A pH above 7 indicates a substance to be basic, a pH below 7 is an indicator of acids, while a pH equal to 7 indicates a neutral substance. And now I can combine Because Kb >> Ka, the solution is basic. So, when NH4Cl is added to water, it generates two ions ammonium ion(NH4+) and a chloride ion(Cl-). Ammonium ions i.e. Strong or Weak - Nitrous acid, Is HCOOH an acid or base or both? In chemistry, a salt is an ionic compound that can be formed by the neutralization reaction of an acid and a base.
