Answer:Vinegar Is 5% Acetic Acid And Its Molarity Is 0.833M.
Explanation:
yes
Don't trust atoms, they make up everything.
How about chemical workers... are they unionized?
Completely natural process with almost no harmful side effects
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
Answer:
The pH of the buffer solution is 4.60.
Explanation:
Concentration of acid = ![[HC_2H_3O_2]=0.225 M](https://tex.z-dn.net/?f=%5BHC_2H_3O_2%5D%3D0.225%20M)
Concentration of salt = ![[KC_2H_3O_2]=0.162 M](https://tex.z-dn.net/?f=%5BKC_2H_3O_2%5D%3D0.162%20M)
Dissociation constant = 
The pH of the buffer can be determined by Henderson-Hasselbalch equation:
![pH=pK_a+\log\frac{[salt]}{[acid]}](https://tex.z-dn.net/?f=pH%3DpK_a%2B%5Clog%5Cfrac%7B%5Bsalt%5D%7D%7B%5Bacid%5D%7D)
![pH=-\log[1.8 \times 10^{-5}]+\log\frac{0.162 M}{0.225 M}](https://tex.z-dn.net/?f=pH%3D-%5Clog%5B1.8%20%5Ctimes%2010%5E%7B-5%7D%5D%2B%5Clog%5Cfrac%7B0.162%20M%7D%7B0.225%20M%7D)
pH = 4.60
The pH of the buffer solution is 4.60.
