Can a weak base neutralize a strong acid?
A strong acid or a strong base will ionize completely, where a weak acid or weak base will only ionize partially.
More volume of a weak acid is needed to neutralize a strong base if the concentrations are equal and vise versa for weak bases and strong acids..
What is the formula for the weakest conjugate base?
:- as the strong acid has high tendency to lose proton its conjugate base will be unstable on accepting proton so it will be the weakest conjugate base.Example HSO4–,
Why is Phenylamine a weak base?
The lone pair of the nitrogen atom in the amine group is “drawn in” towards this delocalisation and this interaction makes the lone pair less available to bond to an incoming H+ ion. … Therefore, phenylamine is a weaker base than ethylamine because its lone pair is less available.
What is the conjugate acid of a weak base?
The conjugate acid of a weak base is a strong acid. Footnotes: 1. The terms “acid” and “base” refer to a Brønsted-Lowry acid and a Brønsted-Lowry base.
Why is a conjugate base of a strong acid weak?
Strong acids have a weak conjugate base. If HCl is a strong acid, it must be a good proton donor. HCl can only be a good proton donor, however, if the Cl- ion is a poor proton acceptor. Thus, the Cl- ion must be a weak base.
What happens when a strong base reacts with a weak acid?
Weak Acid-Strong Base Titrations. A weak acid will react with a strong base to form a basic (pH > 7) solution.
Can a weak acid neutralize a weak base?
Weak acids and weak bases When a weak acid reacts with an equivalent amount of a weak base complete neutralization does not occur. The concentrations of the species in equilibrium with each other will depend on the equilibrium constant, K, for the reaction, which can be defined as follows.
Which solution is most basic?
Barium hydroxide is the most basic solution. This can be proved by calculating the concentration of OH- ions in the solution. The one with the highest OH- concentration is the most basic solution.

Does ClO act as a weak base in water?
As such, it is a strong electrolyte that completely dissociates in solution into Na+, which is a spectator ion, and ClO– ion, which is a weak base with Kb = 3.3 10–7 (Equation 16.35). … We say that the solution is 0.31 M in NaClO, even though some of the ClO– ions have reacted with water.
What makes a base stronger?
Two of the factors which influence the strength of a base are: the ease with which the lone pair picks up a hydrogen ion, the stability of the ions being formed.
How do you know if a base is strong?
The issue is similar with bases: a strong base is a base that is 100% ionized in solution. If it is less than 100% ionized in solution, it is a weak base. There are very few strong bases (see Table 12.2 “Strong Acids and Bases”); any base not listed is a weak base. All strong bases are OH – compounds.
What is weak acid and weak base?
A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. The conjugate base of a weak acid is a weak base, while the conjugate acid of a weak base is a weak acid.
What acts as a weak base in water?
An example of a weak base is ammonia. It does not contain hydroxide ions, but it reacts with water to produce ammonium ions and hydroxide ions. The position of equilibrium varies from base to base when a weak base reacts with water. The further to the left it is, the weaker the base.
Which acid has the stronger conjugate base?
In general, the stronger the acid, the weaker its conjugate base. Likewise, the weaker the acid, the stronger its conjugate base….Strong and Weak Acids and Acid Ionization Constant.AcidConjugate BaseStrong AcidsHCl (hydrochloric acid) (strongest)Cl− (chloride ion) (weakest)H2SO4 (sulfuric acid)HSO4− (hydrogen sulfate ion)HNO3 (nitric acid)NO3− (nitrate ion)5 more rows•Jun 26, 2013
Is NaOH a weak base?
Sodium hydroxide (NaOH) is strong base because it fully dissociates in water to produce hydroxide ions. … While weak bases produce fewer hydroxide ions, making the solution less basic.
What is the strongest base in chemistry?
Here is a list of the most common strong bases.LiOH – lithium hydroxide.NaOH – sodium hydroxide.KOH – potassium hydroxide.RbOH – rubidium hydroxide.CsOH – cesium hydroxide.*Ca(OH)2 – calcium hydroxide.*Sr(OH)2 – strontium hydroxide.*Ba(OH)2 – barium hydroxide.
Is ethylamine a weak base?
This colourless gas has a strong ammonia-like odor. It is miscible with virtually all solvents. It is a nucleophilic base, as is typical for amines.
