c. Slippery feeling  is not a property of an acid

Further explanation

The solution can be divided into three groups namely acid, base and neutral.

This property can be identified by using acid-base indicators such as litmus or universal indicators, or it can be with a pH meter

There are some opinions from experts about acid base

  • 1. According to Arrhenius


An acid is a compound that in water releases H + ions


Example


CH₃COOH (aq) ---> H⁺ (aq) + CH₃COO⁻ (aq)


The number of H⁺ions produced by 1 acid molecule is called valence acid, whereas ions formed after releasing H⁺ ions are called acidic residual ions


Based on the amount of H⁺ ions released, acids can be classified into


  • 1. Monoprotic acid is an acid which releases one H⁺ ion in solution.


Example: HCN, HI, HCl, HBr

    1. Diprotic acid is an acid which releases two H⁺ ions in solution


Example: H₂C₂O₄, H₂SO₄, H₂CO₃

    1. Triprotic acid is an acid that releases three H⁺ ions in solution


Example: H₃PO₄


  • 2. According to Bronstead-Lowry


Acid = donor (donor) proton (H⁺ ion)


Base = proton (receiver) acceptor (H⁺ ion)


NH₄⁺ (aq) + H₂O (l) ⇄ NH₃ (aq) + H₃O⁺ (aq)


From this theory, it is known as the conjugate acid base pair


The conjugate base is an acid which has given a proton


Conjugate acids are bases that have received protons


Acid ⇄ conjugate base + H +


Bases + H + ⇄ conjugate acids

    1. According to Lewis


Acid: accepts an electron pair (acceptor)

Bases: give electron pairs (donors)


Acid Properties:


pH <7


the taste is sour


Corrosive

Make blue litmus paper turn red

Neutralize the base solution (neutralization reaction)

Reacts with bases to produce salt and water

HCl + NaOH -> NaCl + H₂O

Reacts with metals to produce hydrogen gas

2HCl + 2Na ---> 2NaCl + H₂

So in addition to choice C which is a property of bases, choices A, B and D are properties of acid

\(\boxed{{\text{c}}{\text{. slippery feeling}}}\) is not a property of acid.


Further explanation:


Acids and bases can be defined in many ways based on different theories, which are as follows:


1. Arrhenius theory: According to this theory, acid is defined as the one which produces hydrogen or hydronium ions in a solution, while the base is defined as the one which produces hydroxide ions in a solution. Examples of Arrhenius acids include HBr, \({\text{HN}}{{\text{O}}_3}\) and \({{\text{H}}_2}{\text{S}}{{\text{O}}_4}\) while NaOH and KOH are examples of Arrhenius bases.


2. Bronsted-Lowry theory: According to this theory, the acid in the reaction donates a proton while a base is one that accepts a proton. \({{\text{H}}_2}{\text{O}}\) acts as Bronsted acid while \({\text{N}}{{\text{H}}_3}\) is a Bronsted base.


Ammonia is an example of a Bronsted-Lowry base as it accepts protons from the other species like water. Water, therefore, acts as Bronsted-Lowry acid as it donates a proton to other species. (Refer to the attached image)


3. Lewis theory: According to this theory, an acid accepts a pair of electrons to electron-rich species while a base donates electrons to electron-deficient species in the reaction. Examples of Lewis acids are \({\text{B}}{{\text{F}}_3}\), \({\text{S}}{{\text{O}}_3}\) while \({{\text{H}}_2}{\text{O}}\) and ROH are the examples of Lewis base


Acids are ionic compounds that produce positive hydrogen ions when dissolved in water. Ionic compounds are compounds that contain positive metal ions and negative nonmetal ions held together by ionic bonds. Acid is defined as a molecule that can donate a proton or accept an electron-pair. An example of an acid is hydrogen chloride (HCl).


Acids are not  while the bases are  in nature. Hence option c is correct and option a, b and d are incorrect.
