Question

Calculate the hydrogen lon concentration (in ) and the hydroxide ion concentration (in ) in cranberry Juice from its pH (255). (Assume item [H,0*1 (OH) Supporting Materials Supplemental Data Periodic Table Constants and Factors Adonal Materials Section 14.2 My Notes Ask Your Teacher 5. -3 points WAS OSGENCHEM1 14.2.WA.003. What is the pH of an aqueous solution that contains a hydronium ion concentration of 4.4x102 Need Help? My Notes Ask Your Teach 6. -/3 points WAS OSGENCHEM1 14.2.WA.006. ition is 12.45, determine the hydroxide ion concentration of the solution.

Answer 1

Please give me better rattings.

- solution) kw=101x1014 , Temperature = 25° C = 2986 4) Cranberry juice has pH = 2:35 We know, pH = -log [ut] on, 2-35=-log [HH] or log [HI] = ~2-35 no Taking Antilog, we get, ov, (int)> 4.47% 100M We also know, kes [ht] [or] er, 101x10th = 4.470103 [01] Or, [CH]s 1.01 X10'y -14+3 0.226 X10 2 - You 7 x 10 or, [ou]0.226x10" on, Cor] =2.26 *1012 M. - Solutno - ] Gillen in [ht] = 4.48102m 1. Then pH> - 10g [mt] = -log(4-4x102) or, pHs -log(4.4) - log(102) o 2 - log(4.4) 3 2-0.64 : PH: 1136) Solutn: 6) POH= 12.45 We Know , Pol sa log comi],or, 12:45 sa lag Comi] or log [or]= - 12:45 . Taking Antilo g , we get a rom-] = 3.55x1013 M

Thank you.
