Answer:

The rows on the periodic table are called periods. All the elements in a period have valence electrons in the same shell. The number of valence electrons increases from left to right in the period. When the shell is full, a new row is started and the process repeats.

Calculate the [OH-] and the pH of 0.035 M KOH.

DanielleElmas [232]

Answer:

pH

$= 12.54$

OH- concentration 28.84

Explanation:

KOH dissociates into K+ and OH-. The ratio of K+ and OH- ion is 1:1

In any aqueous solution, the H3O+ and OH - must satisfy the following condition -

$[ H_3O^+] [OH^-] = k_w$

$[ H_3O^+] = \frac{k_w}{ [OH^-]}$

$[H_3O^+] = \frac{1 * 10^{-14}}{3.5 *10^{-2}[H_3O^+] = 2.857 * 10^{-13}$ M

pH =

$- log [ H_3O^+]\\- log [2.857 * 10^{-13}]$

pH

$= - [-12.54]\\= 12.54$

pOH $= 14 -$ pH

pOH

$= 14 - 12.54\\= 1.46$

OH concentration $= antilog 1.46$

OH- concentration 28.84
