There were three different ways of defining that.
The first is the Arrhenius definition:
An acid produces hydrogen ions (H+) in a solution and a base produces hydroxide ions (OH-) in a solution.
The second is the Bronsted-Lowry definition:
An acid gives up a proton (H+) to something else and a base takes a proton from something else.
Finally is the Lewis definition:
A Lewis acid accepts a pair of electrons. A Lewis base donates a pair of electrons for bonding.

∙ 12y agoThe most commonly supplied difference is their pH levels. pH is a measure of the acidity or basicity of a solution. Acid=pH that is less than 7.0--- Base=pH that is greater than 7.0. The pH scale rangesfrom 0-14. Water is said to be neutral and right at a pH level of 7.0 An acid (from the Latin acidus meaning sour) is traditionally considered any chemical compound that, when dissolved in water, gives a solution with a hydrogen ion activity greater than in pure water, i.e. a pH less than 7.0. That In addition to this, bases can commonly be thought of as any chemical compound that, when dissolved in water, gives a solution with a pH higher than 7.0
Acids have a pH 7 Water, which is neutral has a pH = 7
According to one of the many theories on acids and bases, acids dissociate in water to form H+ ions. For example, sulphuric acid (H2SO4) will dissociate to form H+ and SO42- ions in water. A strong acid is one which ionised completely in water, while a weak acid is one that is only partially ionised in water. A bases is a compound that when dissolved in water, produced OH- ions. For example, sodium hydroxide NaOH will dissociate in water to form Na+ and OH- ions. A strong bases is one which is ionised completely in water, while a weak acid is one that is only partially ionised in water. Acids have a sour taste and turn blue litmus paper red. Alkalis1 are slippery and turn red litmus paper blue. 1Alkalis are soluble bases.

How indicators can tell the difference between acid and a base?
becase the acid will turn red and the alkile will turn purple
Difference between acid base titration and redox titration?
Acid base titration involves neutralization reaction between an acid and a base. whereas redox titration involves redox reaction between an oxidizing agent and reducing agent.
What is more reactive an acid or a base?
Reactivity depends on into which foreign mixture an acid or base is mixed. The further the difference of pH values between the acid or base and the new system into which the acid or base is added, the greater will be the resultant reactivity.
Why do you use litmus paper to tell the difference between acid and base?
You use litmus paper to tell the difference between acid and base because it is convenient. It is easy to transport and store, it is easy to use and it is easy to the the result, which is a clear change in color.
What is the main difference between acids and base?
Acid compounds will donate hydrogen ions and base compounds will accept hydrogen ions.
Is flammability a example of chemical property?
Yes, because it shows you the difference between an acid or a base. An of course its both an acid and a base?

How can you safely determine the difference between an acid or a base?
The DIFFERENCE ?! I think you mean distinguish an acid from a base, which needs an indicator, like red cabbage solution(turns yellowish with acid, darker with base) Phenolphtaline(Turns violet with a base) Red/Blue litmus paper(RLP turns blue with a base, and BLP turns red with an acid) and finally a pH meter/paper.
What is the main difference between acids and base?
Acid compounds will donate hydrogen ions and base compounds will accept hydrogen ions.
What is the difference between neutralization salt?
Salts are the products of a reaction between an acid and a base; this reaction is called neutralization reaction.
What is the difference between neutralization and salts?
Salts are the products of a reaction between an acid and a base; this reaction is called neutralization reaction.
Difference between a strong acid and a strong base?
An acid produces H+ ions when they are put in water. A base produces OH- ions when they are put in water.
What describes species that are related by a difference in protons?
the conjugate acid/base of an acid-base pair
