Answer: [OH-] = 1.8 x 10^-7 Explanation: pH + pOH = 14 –> 6.93 + pOH = 14 *subtract 6.93 from both sides pOH = 7.07 –> 10^pH => 10^-6.93 => 1e – 6.93 [H+] –> H+ x OH- = 1 x 10^-6.93 *divide H+ from both sides –> [OH-] = 1.17 x 10^-7 or 1.8 x 10^-7 Log in to Reply
Answer:
[OH-] = 1.8 x 10^-7
Explanation:
pH + pOH = 14 –> 6.93 + pOH = 14 *subtract 6.93 from both sides
pOH = 7.07
–>
10^pH => 10^-6.93 => 1e – 6.93 [H+]
–>
H+ x OH- = 1 x 10^-6.93 *divide H+ from both sides
–>
[OH-] = 1.17 x 10^-7 or 1.8 x 10^-7
