There are three definitions for acids and bases.
Arrhenius definition: An acid is a substance that produces hydrogen (H+) ions in water while a base produces hydroxide (OH-) ions.
Bronsted-Lowry definition: An acid gives up or donates a proton (H+) to another molecule while a base accepts a proton.
Lewis definition: An acid accepts an electron pair in bonding to another molecule/ion while a base donates and electron pair.
Note that if a substance meets one of the first two definitions it probably meets the others as well.
What else can I help you with?
What kind of reaction is nitric acid and potassium carbonate is?
This is considered an acid/base reaction.
Is an acid and a base both reactants?
Yes, in a chemical reaction, an acid and a base are both considered reactants. They react with each other in a neutralization reaction, typically producing water and a salt. This interaction is fundamental in acid-base chemistry, where the acid donates protons (H⁺), and the base accepts them.
What combinations of compounds will make a buffer when mixed?
In order to have an effective buffer, one needs to have a weak acid or a weak base, and the salt (conjugate) of that weak acid or weak base. Examples would be :weak acid/conjugate base: acetic acid/sodium acetateweak base/conjugate acid: ammonia/ammonium chloride
Is penicillin a base or a acid?
Penicillin is an acid. It contains a beta-lactam ring that confers its antibacterial properties, but the molecule overall is considered an acid due to its chemical structure.
What would be the conjugate pair for a strong base?
The conjugate pair for a strong base is a weak acid. When a strong base, such as sodium hydroxide (NaOH), dissociates in water, it produces hydroxide ions (OH⁻), which can then react with a weak acid to form its conjugate base. For example, if we take the strong base sodium hydroxide, its conjugate pair would be the weak acid water (H₂O), which can donate a proton to form hydroxide ions. Thus, the conjugate acid-base relationship involves a strong base and its corresponding weak acid.
What is the exact pH of acid?
Well, there really is no "exact" pH of an acid. An acid can be a certain pH, before it is considered a base, and to change an acid to a base would be called titration, but lets not get carried away. The pH of an acid can be anywhere between 0-6 on the pH scale, 7 would be neutral, and 8-14 would be considered a base.
Is water considered an acid or a base?
Water is considered neutral, neither an acid nor a base.
Is an antacid considered an acid or a base?
An antacid is considered a base.
Is hydronium ion considered an acid or a base?
Hydronium ion is considered an acid.
Is NH4NO3 a strong acid and a weak base?
It is the product of a strong acid and a weak base, but is itself a mildly acidic salt.
Is CH2O an acid or a base?
CH2O, which is formaldehyde, is not an acid or a base. It is considered a neutral compound.
Is ch2o a Lewis acid or base?
Formaldehyde (CH2O) is not typically considered a Lewis acid or base on its own. Its role as an acid or base would depend on the specific reaction conditions and the species it is interacting with.
Is HCl considered a base or an acid in chemical reactions?
HCl is considered an acid in chemical reactions.
Is ammonia considered a strong acid?
No, ammonia is not considered a strong acid. It is actually a weak base.
Is coffee considered an acid or a base?
Coffee is considered to be acidic.
Is coffee considered to be a base or an acid?
Coffee is considered to be acidic.
Is HCl considered a weak base?
HCl is not considered a weak base; it is actually a strong acid.
