Mell What is the combination of an acid and a base?
When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.
Can cation and anion act as acid and base?
This particular case is unusual, in that the cation is as strong an acid as the anion is a base (pKa ≈ pKb). Consequently, the two effects cancel, and the solution remains neutral. With salts in which the cation is a stronger acid than the anion is a base, the final solution has a pH < 7.00.
What is produced when a base reacts with an acid?
Acids react with bases to form a salt and water.
Why does a salt containing a cation from a strong base and an anion from a weak acid form a basic solution?
Basic salts result from the neutralization of a strong base with a weak acid. Acid salts result from the neutralization of a strong acid with a weak base. For salts in which both cation and anion are capable of hydrolysis, compare Ka and Kb values to determine the solution ‘s resulting pH.
What happens if you mix two acids?
Hence, when two acids are mixed together, no reaction occurs. But when strong acid is mixed with weak acid then the reaction occurs to produce salts. Note: Weak acids are capable of liberating less hydrogen ions this gives them a higher pH.
Are anions acidic or basic?
Basic Salts In general, anions A- can be considered the conjugate base of the acid HA. Depending on the strength of the corresponding acid: • A-, the conjugate base of a weak acid, acts as a weak base. A-, the conjugate base of a strong acid, acts as a pH-neutral.
Is Ag+ acidic or basic?
Re: Why Ag+ is a Lewis acid not base? Ag+ is an electron pair acceptor (Lewis acid) because it is positively charged. As I discussed in class electrons are electrostatically attracted to the positive charge.
What is acid and base with example?
Acid and base are the form of chemicals which plays a vital role in chemistry and are readily available in our daily life. Examples of acids include citric acid and lactic acid present in lemons and in dairy respectively. Some examples of bases include cleaning products like bleach and ammonia.
What is a base used in toothpaste?
Magnesium hydroxide is a base used in toothpaste.
Is nahco3 acidic or basic?
Sodium bicarbonate is a weak base with pH slightly above 7.
Is Ba2+ acidic or basic?
Cations of the group 1A metals (Li+, Na+, K+, Rb+, Cs+) and the group 2A metals (Ca2+, Sr2+, Ba2+) do not react with water and are nonacids. They do not affect the pH of the solution. Some highly-charged, rather small cations can produce an acidic solution. Examples would be hydrated Al3+, Zn2+, and Fe3+ ions.
What are the cations and bases of an ionic compound?
Summary. Ionic compounds all contain at least one cation and at least one anion. Acids produce H^ (+) cations. Bases provide the oxide or hydroxide anion that reacts with hydrogen cations to form the water. There are different definitions of “acids” and of “bases”.
What happens when anion and cation combine to form an acid?
Anions and cations combine to form ionic compounds so that the charges cancel out. An acid contains two ions, a hydrogen cation plus one other which has a negative charge to cancel the positive charge of the hydrogen, so is an anion …
How to tell if a chemical is an anion or a cation?
A base also contains 2 ions, usually a metal cation (or ammonium) with a positive charge plus either an oxide anion = O^ (2-) anion or a hydroxide anion = OH^ (-) anion. Any base will react with any acid to form a salt plus water ONLY. To name the salt, take the metal cation from the base and combine it with the anion of the acid …
What happens when a base reacts with a cation?
Assess the acid–base properties of the cation and the anion. If the cation is a weak Lewis acid, it will not affect the of the solution. If the cation is the conjugate acid of a weak base or a relatively highly charged metal cation, however, it will react with water to produce an acidic solution.
