A strong base is one that completely dissociates in water. Common examples are sodium hydroxide (NaOH) and postassium hydroxide (KOH). Both will fully dissociate into a metal ion (either Na+ or K+) and hydroxide ions (OH-). If you add a certain concentration of a strong base, the concentration of OH- in that solution is equal to the concentration of the base. This is not the case for weak acids, which do not dissociate completely. See the Web Links to the left of this answer for a complete list of the strong bases and more information.
A strong acid will produce the most hydronium ions in an aqueous solution, as it completely dissociates into hydronium ions and anions. Acids such as hydrochloric acid, sulfuric acid, and nitric acid are examples of strong acids.
The strong and irritating smell in a basic aqueous solution is often due to ammonia, which has the chemical formula NH3. Ammonia is a common base and its presence can be detected by its distinctive odor.
After this reaction a salt is formed.
Neither, it is a neutral salt (conjugated with the strong acid HCl)
No, an aqueous solution of a base typically contains hydroxide ions (OH-) along with other cations and anions derived from the base compound dissolved in water. So, it may contain multiple elements, not just two.
No, H2SO4 (sulfuric acid) is not a base; it is an acid. It is a strong acid that donates protons in aqueous solutions.
No, you mixed it up. Hydronium H3O+ from strong acid and Hydroxide OH- from strong base (alkaline)
"Ammonia", NH3, is a fairly strong base having at 1M concentration in aqueous solution a pH of 11.6
No, SO4-2 (sulfate ion) is a weak base. It does not readily accept protons in aqueous solutions to act as a base.
basic in nature
A dilute aqueous solution of a weak base contains molecules of the weak base and some hydroxide ions generated from the base's reaction with water. The concentration of hydroxide ions is lower than a strong base due to incomplete ionization of the weak base in water.
A strong acid will produce the most hydronium ions in an aqueous solution, as it completely dissociates into hydronium ions and anions. Acids such as hydrochloric acid, sulfuric acid, and nitric acid are examples of strong acids.
Yes, sulfuric acid in its aqueous form is considered a strong acid.
The strongest base in aqueous solution is the hydroxide ion (OH-), as it readily accepts protons to form water. Other strong bases include alkali metal hydroxides such as sodium hydroxide (NaOH) and potassium hydroxide (KOH).
The reactants are a strong base and a weak acid.
NaNO3 is a salt composed of a strong acid (HNO3) and a strong base (NaOH). Since both the acid and the base are strong, NaNO3 dissociates completely in water to form Na+ and NO3- ions. Therefore, NaNO3 is considered a neutral salt and does not act as either an acid or a base in aqueous solution.
No, CsOH (cesium hydroxide) is a strong base because it dissociates completely in water to produce Cs+ ions and OH- ions. This makes it highly effective at accepting protons, leading to a high pH in aqueous solutions.
