Answer to Question #192180 in General Chemistry for Joha

Question

A buffer solution is prepared via adding solution A (Sodium dihydrogen phosphate 27.6 gm up to 1000mL distilled water) and solution B (Disodium hydrogen phosphate 5.362gm up to 100mL distilled water). During preparation, 1000 mL buffer is prepared via adding 80mL of solution B to 920mL of solution A. Show a theoretical approach to calculate the pH of the buffer solution

Answer 1

pH of the buffer solution=9.37
