sodium citrate and water
When citric acid (C6H8O7) is combined with sodium hydroxide (NaOH), a neutralization reaction occurs. The reaction can be represented by the following balanced chemical equation:
C6H8O7 + 3NaOH → 3H2O + Na3C6H5O7
In this reaction, citric acid, a weak acid, reacts with sodium hydroxide, a strong base. The result is the formation of water (H2O) and sodium citrate (Na3C6H5O7).
Sodium citrate, also known as trisodium citrate, is an odorless crystalline powder with a sour taste. It is commonly used as a food additive, particularly as a flavoring agent and acidity regulator. Sodium citrate can also be used as an anticoagulant in medical applications or as a pH buffer in various chemical processes.
To determine the final product of citric acid combined with sodium hydroxide, it is important to understand the concept of neutralization reactions and how to balance chemical equations. By balancing the equation, you can identify the substances involved and their respective quantities in the reaction.
