Question

hello, my name Devin im in this online class and i wanna double-check my hw before i submit it. please and thank you. have a great job. i appreciate your hard work.

all of the answers should be in the form of (m)

13. For each hydrogen ion concentration listed, calculate the solution as the concentration of hydroxide ion in the solution. Indicate whether each solution is acidic or basic

.(a) [H⁺] = 4.85 10^-8M

(b) [H⁺] = 8.92 10^-3M


(c) [H⁺] = 7.03 10^-5M

(d) [H⁺] = 1.31 10^-12M

(e) pH = 8.92
  

(f) pH = 6.97
  

(g) pH = 1.19

(h) pH = 7.02
  

(i) pOH = 4.30
  

(j) pOH = 6.93
  

(k) pOH = 12.43
  

(l) pOH = 1.43

Answer 1

Acidic solution has more concentration of H+ ion than concentration of hydroxide ion.
