(aq) (s) Task 2. You need to make a buffer solution that has a pH of 7 + 53/100 (e.g. 7.63) at SATP. You have unlimited 2.00M HCL and NaOH pellets. You start with 53/100 moles of a weak acid "HA", K = 430 x 10-¹0, already dissolved in 2.0 L of water. (a) How to make this buffer? Explain thinking process. (b) Would adding 430 mM, 430 mL of HCl going to seriously affect the pH of the buffer? Explain in 40 words.
