The equation for the reaction between hydrated oxalic acid (H2C2O4·2H2O) and sodium hydroxide (NaOH) is:
H2C2O4·2H2O + 2NaOH → Na2C2O4 + 4H2O
Di-carboxylic acid (such as oxalic acid) neutralizes with sodium hydroxide to form sodium salt of the di-carboxylic acid and water. The general word equation is di-carboxylic acid + sodium hydroxide -> sodium di-carboxylate + water.
Phenolphthalein is used as an indicator in the titration of oxalic acid against sodium hydroxide because it undergoes a color change at the pH region where the reaction between oxalic acid and sodium hydroxide is neutralized. Oxalic acid is a diprotic acid, meaning it requires two equivalents of sodium hydroxide to be fully neutralized. Phenolphthalein changes color at a pH of around 8.2-10, which is ideal for indicating the endpoint of the titration.
The word equation for the reaction of sulfuric acid and sodium hydroxide is: sulfuric acid + sodium hydroxide → sodium sulfate + water.
Sodium hydroxide plus hydrochloric acid equals sodium chloride plus water.
The reaction between sodium hydroxide and sodium carbonate can be represented by the following equation: 2NaOH + Na2CO3 -> 2Na2CO3 + H2O
Di-carboxylic acid (such as oxalic acid) neutralizes with sodium hydroxide to form sodium salt of the di-carboxylic acid and water. The general word equation is di-carboxylic acid + sodium hydroxide -> sodium di-carboxylate + water.

Sodium Hydroxide + Hydrocloric acid --> Sodiumchloride + Water
Absolutely not. There is no sodium in that equation whatsoever.
Sodium hydroxide plus hydrochloric acid equals sodium chloride plus water.
Pyrogallic acid and sodium hydroxide is used to provide anaerobiosis.
The reaction between sodium hydroxide and sodium carbonate can be represented by the following equation: 2NaOH + Na2CO3 -> 2Na2CO3 + H2O
Phenolphthalein is a suitable indicator for the titration of oxalic acid with sodium hydroxide. It changes color from colorless to pink at the endpoint of the titration when the acid has been completely neutralized.
The balanced equation for the reaction between a fatty acid (such as oleic acid) and sodium hydroxide is: Fatty acid + Sodium hydroxide -> Soap (sodium salt of the fatty acid) + Water
The chemical equation for the reaction of sodium with water to produce sodium hydroxide and hydrogen gas is: (2Na + 2H_2O \rightarrow 2NaOH + H_2)
The word equation for sodium reacting with water is: sodium + water → sodium hydroxide + hydrogen gas.
