Which of the following weak acids has the strongest conjugate base. HNO2 weak acid and NaNO3 Clear my choice To prepare a buffered solution with pH45 which pair of conjugate acid-base you should use. Select the best answer a.

-The molecular form of the weak acid does exist in solution. D HCl and HC2H3O2. HCO3 weak acid and NaCO3 b.

A HNO3 and H2CO3. Correct option is D Weak acids dissociates partially only eg in aqueous solution carbonic acid and acetic acid behave as weak acids. H3PO4 HNO2 H2SO3 HClO HClO2 HF H2S CH3COOH -Solutions of weak acids have a low concentration of H.

If HCl is added which ion will react with the extra hydrogen ions from the HCl to keep the pH from changing. A acetic acid Ka 18 10-5 B nitrous acid Ka 45 10-4 C dihydrogen phosphate ion Ka 62 10-8 D hydrocyanic acid Ka 40 10-10 E benzoic acid Ka 63 10-5. Click again to see term.

2 Which of the following statements is NOT true for weak bases. Which of the following statements is NOT true for strong acids. Acetone ethanol ethanal cyclohexanol phenol.

HA aq OH aq A aq H 2O 1 An acid-base titration can be monitored either through the use of an acid-base indicator or through the use of a pH meter. 1Among the given acids HCN is weak acid Hence option 3rd is correct option. Acetic acid or CH 3 COOH is a very common weak acid because it doesnt.

E HBr and H3PO4. For example the dissociation of a weak acid HA is written. Only small quantities of indicator are added to a solution.

CH3COOH weak acid and KCH3COO d. The correct answer is CH3COOH. The substance CH3CH22NH is considered to be A.

H2SO4 has a pKa1 of 3 so it dissociates very easily. The acid and base forms of the indicator are different colors. Often called acetic acid.

Acid-base indicators are derived from weak acids. Therefore pKa -log Ka. Tap card to see definition.
