How do acids and bases interact in a buffer solution?

  • Thread starter laker_gurl3
  • Start date
In summary, the first conversation includes a question about the reaction that occurs when calcium oxide is added to water, and a question about the pH of a buffer solution after adding a small amount of NaOH. The second conversation includes a question about the resulting pH when .75 mol of acetic acid is dissolved in 3.0L of water.

1.) i would like to know if this is right
What is the reaction that occurs when calcium oxide is added to water?
is it : CaO + H2o --> Ca(OH)2

and the second question which i have no idea to is..

Consider the buffer equilibrium:

HF(aq) + H2O(l) ---> H30(aq) + F(negative)(aq)
the HF has high conc.
The H3O has low conc.
and the F has high conc.
Using le Chat's principle, what happens to the pH of the buffer solution when a small amount of NaOH is addeD?!
thanks a bunch u guys!

help.. :(
anyone..specially the second question

yikes, i also have another question... please help.. :(

What pH results when .75 mol of acetic acid is dissolve din enough water to make 3.0L of solution..?
 

1. What is the difference between an acid and a base?

An acid is a substance that donates hydrogen ions (H+) in a solution, while a base is a substance that accepts hydrogen ions or donates hydroxide ions (OH-) in a solution. Acids are typically sour in taste and turn litmus paper red, while bases are typically bitter in taste and turn litmus paper blue.

2. How do you measure the strength of an acid or base?

The strength of an acid or base is measured using the pH scale, which ranges from 0 to 14. A pH of 7 is considered neutral, while a pH below 7 is acidic and a pH above 7 is basic. The lower the pH, the stronger the acid and the higher the pH, the stronger the base.

3. How do you neutralize an acid or base?

To neutralize an acid or base, you can use a process called titration. This involves adding a known amount of a base to an acid or vice versa until the solution reaches a neutral pH of 7. Another way to neutralize an acid or base is to mix them together in equal amounts, which will also result in a pH of 7.

4. What are some examples of common acids and bases?

Some common acids include vinegar (acetic acid), lemon juice (citric acid), and stomach acid (hydrochloric acid). Some common bases include baking soda (sodium bicarbonate), milk of magnesia (magnesium hydroxide), and ammonia (NH3).

5. How are acids and bases used in everyday life?

Acids and bases are used in a variety of ways in everyday life. Acids are used in cleaning products such as vinegar and lemon juice, while bases are used in baking soda and soap. They are also important in food and beverage production, as well as in medicine for things like stomach acid regulation and antacids.
