In summary, the reaction between acetic acid and ethylene diamine results in the formation of a salt, with the structural formulas for both compounds drawn below. The balanced chemical equation for the reaction is C2H4O2 + C2H8N2 --> 2H2O + C4H8N2, where both amine groups can accept a proton. However, due to the weak acid and base nature of the compounds, a more precise understanding of the solution would require consideration of all acid/base equilibria.

Consider the Acid-Base reaction of acetic acid (C2H4O2) with ethylene diamine (C2H8N2) to form the corresponding salt. Then the structural formulas for acetic acid and ethylene diamine were drawn below this.
Write a balanced chemical equation for the reaction, noting both amine groups can accept a proton.

I know that acid + base = water + salt

I'm not sure if what I've come up with is right or not... I don't remember the teacher ever going over anything like this...

C2H4O2 + C2H8N2 --> 2H2O + C4H8N2

No water in products, amine groups get protonated.
 
  • #3
Would the product be C2H3O2- + C2H9N2+.. and would this ionize and form a salt?
 
  • #4
Diamine can get protonated twice.

Basically you will have a salt C2H10N2(2+)(2C2H3O2(-))2.

However, that's not whole truth - acetic acid is a weak acid, ethylene diamine is a weak base, so if you will need precise information about the solution, you will have to take all acid/base equilibria into accounts.
 

1. What is an acid-base reaction?

An acid-base reaction is a chemical reaction that occurs between an acid and a base. Acids are substances that release hydrogen ions (H+) in solution, while bases are substances that release hydroxide ions (OH-) in solution. During an acid-base reaction, the hydrogen ions and hydroxide ions combine to form water and a salt. This type of reaction is also known as a neutralization reaction.

2. How do you identify an acid-base reaction?

An acid-base reaction can be identified by the presence of an acid and a base, as well as the formation of water and a salt as products. Another way to identify an acid-base reaction is by testing the pH of the solution before and after the reaction. If the pH decreases, it is an acid-base reaction, as acids have a lower pH than bases.

3. What are some examples of acid-base reactions?

Some common examples of acid-base reactions include the reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) to form water and sodium chloride (NaCl), the reaction between vinegar (acetic acid) and baking soda (sodium bicarbonate) to form carbon dioxide gas, and the reaction between stomach acid and antacids to neutralize stomach acid and relieve heartburn.

4. How does temperature affect acid-base reactions?

The rate of an acid-base reaction can be affected by temperature. Generally, increasing the temperature will increase the rate of the reaction, as more energy is available for the reactant particles to collide and form products. However, for some acid-base reactions, such as the reaction between hydrochloric acid and sodium hydroxide, an increase in temperature can also cause the reaction to shift towards the reactants, resulting in a slower reaction.

5. What is the importance of acid-base reactions?

Acid-base reactions are important in many areas of science and everyday life. They play a crucial role in maintaining the pH balance in our bodies and in the environment. They are also used in various industrial processes, such as in the production of fertilizers, cleaning agents, and food products. Understanding acid-base reactions is essential for many scientific fields, including chemistry, biology, and environmental science.
