Question

Why is NaOH is a strong base and HCl a strong acid?

Answer 1

Answer:

HCl and NaOH are strong acid and strong base respectively and their titration curves are similar (shape of curve) in different concentrations. NaOH + HCl = NaCl + H 2 O. Both reactants and products are in aqueous state. Important factors and equations of HCl + NaOH reaction and its titration curve. HCl and NaOH reacts in 1:1 ratio (in same amount).

Answer 2

NaOH, dissociates completely in aqueous solution to form sodium  cations, it is classified as a strong base .

HCl molecules dissolve, they split into two categories of ions H+ and Cl- . HCl is a strong   acid.

Explanation:

• Make a comparison HCl, NaOH, and NaCl. Water is a weaker acid than HCl. The base NaCl is weaker than the basis NaOH.
• Strong acids and bases react to produce lighter acids and bases.
• Strong bases are based upon the fact that they completely dissociate in aqueous solution.
• Because sodium hydroxide, NaOH, dissociates completely in aqueous solution to form sodium cations, Na+, and hydroxide anions, OH−, it is classified as a strong base in this case.

•        When HCl molecules dissolve, they split into two categories of ions H+ and Cl-.

• Because it dissociates almost completely, HCl is a strong acid.
• A weak acid, such as acetic acid (CH3COOH), on the other side, does not dissociate effectively in water, and many H+ ions remain bound up within the molecule.
