Consider a buffer solution prepared from HOCl and NaOCl. Which is the net ionic equation for the reaction that occurs when NaOH is added to this buffer?
A buffer is formed by dissolving 5g of sodium benzoate, C6H5COONa, and 6g of benzoic acid, C6H5COOH (Ka =6.5 x 10-5) in 1 L of water.
Buffer Problem
What is the pH of the buffer that has 0.81M of CH3COOH and 0.21M CH3COO-? KCH3COOH=1.8x10^-5
Now if we added 0.14M of HCl what is the new pH of the buffer? (ICE table since we need to consider the values at EQUILIBRIUM to find the pH)
