CAN YOU PLEASE EXPLAIN HOW TO DETERMINE METHOD I SHOULD USE TOFIND THE PH IN SUCH PROBLEMS. WHAT RULES SHOULD I FOLLOW OR THINKOF TO DETERMINE SUCH QUESTIONS. (STRONG ACID, STRONG BASE, BUFFER1, BUFFER 2, WEAK ACID, WEAK BASE ETC)
PLEASE: dont solve if you dont explain briefly, and explain tome how I can determine it by myself.
The acid H2A has Ka1 = 2.00 ∙ 10-5 and Ka2 = 5.00 ∙ 10-9. Wehave a buffer consisting of 0.0300 moles of HA– and 0.0100 moles ofA2– and adds 0.0500 moles of H3O +. What kind of system do we haveand how to calculate the pH? Buffer 1 = H2A / HA– Buffer 2 = HA– /A2–
