I have a few questions relating to ph and whatnot..
1) Calculate the pH of 0.0010 M Ca(OH)2 solution. (to2 decimal places)
2) Determine the pH of a KOH solution made by mixing 0.251 g KOHwith enough water to make 1.00 � 102 mL of solution.
3) Calculate the pH of 0.0171 butanoic acid, Ka=1.52x 10-5. Answer in 4 significant figures.
4) Calculate the pH of 0.00000M C5H5Nsolution. Kb=1.5 x 10-9. Answer in 3 decimalplaces.
5) Calculate the pKa of a 0.080M HOCl solution with a pH of3.22.
6) A solution containing NH3(aq) andNH4Cl(aq) has a pH of 9.5. What is the[NH3]/[NH4+] ratio in thissolution? For ammonia, Kb = 1.8 � 10�5.
