The ionization constant (Ka) is the equilibrium constant for the dissociation of a weak acid in water. It measures the strength of an acid. A higher Ka value indicates a stronger acid.

Acids have a pH less than 7, while bases have a pH greater than 7. A pH of 7 is considered neutral, such as pure water. Related Questions: Define and give examples of Arrhenius acids? Why H⁺ ion acts as a Lewis acid? Why BF₃ acts as a Lewis acid? Define a conjugate acid-base pair. … Read more
Neutralization reaction: A neutralization reaction is a chemical reaction between an acid and a base that produces water and a salt. For example, HCL + NAOH → NACL + H2O Related Questions: Define and give examples of Arrhenius acids? Why H⁺ ion acts as a Lewis acid? Why BF₃ acts as a Lewis acid? Define … Read more
Indicators are substances that change color to signal the endpoint of an acid-base titration. They help to visually indicate when the acid has been completely neutralized by the base (or vice versa).

A conjugate acid-base pair consists of two species that differ by one proton (H⁺). The acid donates a proton, and the base accepts it. Example: NH3 + H2O ⇔ NH4+ + OH¯ In the reaction. NH3 and NH4+ , form a conjugate pair, as do H2O and OH¯. Related Questions: Define and give examples of Arrhenius … Read more
Because BF₃ can accept an electron pair from a donor, which is the characteristic behavior of a Lewis acid. Related Questions: Why H⁺ ion acts as a Lewis acid?
