scienceattech.com182 Take 100. mL of the previous buffer (0.05 M tris / 0.075 M tris-HCl), and add 5.0 mL of 0.10 M HCl. What is the pH of the mixture? The HCL should react with the basic component of the buffer - changing it to its conjugate acid: We need to find out the NEW concentrations of all the species in the buffer solution.
