   According to the Bronsted Lowry definition, some substances can act as acids or bases (are called amphoteric) For example: NH3 + H2O ---> NH4+ + OH-(base) (acid) Reverse Reaction: NH4+ + OH- ---> NH3 + H2O (acid) (Base) In this reaction the the base (NH3) in the forward reaction becomes an acid in the reverse reaction which is an example of a ...

   What is an example of an acid and a base?

   • The earliest definition of acids and bases is Arrhenius's definition which states that: A base is a substance that forms hydroxide ions OH - when dissolved in water. For example, hydrochloric acid (HCl HCl) is an acid because it forms H+ H + when it dissolves in water. HCl(g) ⟶ Water H+(aq) +Cl−(aq) H C l (g) ⟶ Water H + (a q) + C l − (a q)

   What are the properties of acids and bases?

   • The general properties of acids and bases are the following. Acids taste sour, e.g., citrus fruits taste source because of citrus acid and ascorbic acid, i.e., vitamin C, in them. Basic (alkaline) substances, on the other hand, taste bitter. Basic (alkaline) substances feel soupy, while acidic substances may sting.

   Do acids and bases neutralize each other?

   • Acids and bases neutralize each other. Hydrochloric acid is found in the stomach that helps digestion. Excess hydrochloric acid may cause acid burns—antacids like milk of magnesia are bases that help by neutralizing excess acid in the stomach.

   Is HCL an acid or a base?

   • HCl is an acid according to the arrhenius definition because when placed in water it ionizes completely to form H+ ions and Cl- ions. In an aqueous solution the H+ ion binds to a water molecule ... ... NaOH is a base according to the Arrhenius definition because it produces OH- ions. When NaOH is added to water, it dissociates into component ions.

   How does hydrochloric acid (HCl) affect a base?

   • Hydrochloric acid (HCl) is an acid that donates a proton. Its conjugate base, chloride ion (Cl-), is a base that accepts a proton. The better an acid is at losing protons, the worse its conjugate base will be at accepting them. Conversely, the better a base is at accepting protons, the worse its conjugate acid will be at losing them. For instance, litmus paper turns red in the presence of an acid and blue in the presence of a base.

   Which base is the most acidic?

   • Thus, acid strength decreases with the loss of subsequent protons, and, correspondingly, the pKa increases which indicate it is the most basic. The conjugate base of ClO3 − has a much smaller charge to volume ratio, thus most stable and acidic. 5. CF3S −
