A reaction between acetic acid and sodium hydroxide forms water and sodium acetate. Is this reaction endothermic or exothermic?
acid-base reactions are exothermic in nature
CH3COOH + NaOH -----------> CH3COONa + H2O
it is simple example of acid-base reaction
so it is exothermic reaction.

in a reaction between calcium hydroxide and acetic acid if the acetic acid is in excess. What would be the observation? what will be the difference between this reaction with the calcium carbonate and acetic acid?
how to write a dissociation reaction for a buffer containing acetic acid and sodium acetate
For a buffer made from sodium acetate and acetic acid, the Ka of acetic acid is 1.8E-5. What mass of sodium acetate (NaCH3CO2) must be added to 2.50 L of 0.68 M acetic acid to make a buffer solution with pH = 5.75? The answer should be in two significant figures.

In The reaction between calcium hydroxide and acetic acid if acetic acid is in excess. 2CH3COOH + Ca(OH)2 → (CH3COO)2Ca + 2H2O and 2CH3COOH + CaCO3 → (CH3COO)2Ca + H2O + CO2 a)What would be the observation? b)what will be the difference between this reaction with the calcium carbonate and acetic acid? c)which of the excess reactants and products are expected to remain?
Given 1 M solutions of acetic acid and sodium acetate, and distilled water, describe the preparation of 1 L of 0.1 M acetate buffer at pH = 5.4. The relevant pKa is 4.76.
" Determine the amount of sodium acetate needed to prepare 50.0 mL of acetic acid/sodium acetate buffer having a H of 5.0 using approximately 0.100 M acetic acid. Check the concentration of the acetic acid in the laboratory and use this exact concentration for your calculation. For acetic acid Ka= 1.8 x 105." The answer is 0.75g NaC2H3O2. But I need to show the equation steps. Any help?
You are making a pH 5.0 buffer with acetic acid (pKa = 4.75) and sodium acetate. You want the total concentration of acetate ([acetic acid] + [sodium acetate] ), to be 0.50 M. What concentrations of acetic acid and sodium acetate do you use to make your buffer? acetic acid sodium acetate
