Weak Acid-Weak Base Neutralization. A weak acid, weak base reaction can be shown by the net ionic equation example: \(H^+ _{(aq)} + NH_{3(aq)} \leftrightharpoons NH^+_{4 (aq)} \) The equivalence point of a neutralization reaction is when both the acid and the base in the reaction have been completely consumed and neither of them are in excess Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH.It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −.. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe chemical burns.It is highly soluble in water, and readily Table \(\PageIndex{1}\) gives the ionization constants for several weak acids; additional ionization constants can be found in Table E1. At equilibrium, a solution of a weak base in water is a mixture of the nonionized base, the conjugate acid of the weak base, and hydroxide ion with the nonionized base present in the greatest concentration. In this reaction, the base accepts a proton from water to form hydroxide and the conjugate acid, BH + Both molecules act as weak bases. From soaps to household cleaners, weak bases are all around us. Amines, a neutral nitrogen with three bonds to other atoms (usually a carbon or hydrogen), are common functional groups in organic weak bases.
Weak acids are relatively common, even in the foods we eat. But we occasionally come across a strong acid or base, such as stomach acid, that has a strongly acidic pH of 1-2. By definition, strong acids and bases can produce a relatively large amount of hydrogen or hydroxide ions and, as a consequence, have a marked chemical activity.
Salts of Weak Acids and Strong Bases. When we neutralize a weak acid with a strong base, we get a salt that contains the conjugate base of the weak acid. This conjugate base is usually a weak base. For example, sodium acetate, NaCH 3 CO 2, is a salt formed by the reaction of the weak acid acetic acid with the strong base sodium hydroxide:
Verified by Toppr. The correct option is D it is only partially ionised. Solution:- (D) it is only partially ionised. N H 4OH is a weak base because it partially ionised in water and produce a small amount of hydroxide ions (OH −). N H 4OH ⇌ N H 4+ +OH −. Was this answer helpful?

Whether magnesium hydroxide is a strong or weak base is a matter of disagreement. Usually it is considered a weak base because of its low solubility. Whether it's a strong or weak base in terms of dissociation is not completely known. IUPAC reports a single $\mathrm{p}K_\mathrm{b}$ value, generally between 2 and 3, based on hydrolysis
