Final answer:
The reaction between NaOH and malic acid results in a neutralization reaction that produces a salt and water, without the release of carbon dioxide or precipitation of a solid.
Step-by-step explanation:
When NaOH reacts with malic acid, the result is a neutralization reaction leading to the formation of a salt and water. This reaction is typical of an acid-base neutralization, where the hydroxide ions (OH-) from the strong base NaOH react with the hydrogen ions (H+) from the malic acid to form water (H2O), and the remaining components of the acid and base form an ionic compound, which is the salt. Since malic acid does not contain carbonate or bicarbonate ions, there will be no release of carbon dioxide. Also, there is no formation of an insoluble solid, or precipitation, in this particular reaction.
