4 days ago · Sodium acetate is the sodium salt of acetic acid, which can be formed by the reaction of sodium hydroxide which is a base and acetic acid. They undergo an acid-base reaction and form salt and water. The reaction is shown below, \[NaOH\, + C{H_3}COOH \to C{H_3}COONa + {H_2}O\]
4 days ago · Hence, the indicator used for the titration of oxalic acid with sodium hydroxide is phenolphthalein. During the titration, oxalic acid is taken in the burette. Aqueous solution of sodium hydroxide is placed in the conical flask and one or two drops of phenolphthalein indicator are added.
4 days ago · The neutralization reaction between sodium hydroxide and sulphuric acid can be represented by the following chemical equation: NaOH(aq) + H2SO4(aq) → Na2SO4(aq) +H2O(l) N a O H ( a q) + H 2 S O 4 ( a q) → N a 2 S O 4 ( a q) + H 2 O ( l) Note: Neutralization reaction is a highly exothermic reaction which means that a lot of heat is evolved ...
