What is the pH of a 0.235 M Ba(OH)2 solution?

Chemistry
1 answer:
Fynjy0 [20]2 years ago
6 0

Answer:

13.672

Explanation:

2 moles of OH in Ba(OH)₂

0.235 M × 2 mol OH = 0.47 M OH

pOH = -log[OH-] ; pOH = -log[0.47 M OH] ; 0.328 = pOH (consider significant figures)

14 - pOH = pH because pH + pOH = 14

14 - 0.328 = 13.672 [there are three decimal places after the OH concentration, so there should be in the answer as well - 13.<u>672</u>]

Which statement best explains why magnesium and chlorine combine in a 1:2 ratio?
denpristay [2]

The statement that best explains why magnesium and chlorine combine in a 1:2 ratio is; Magnesium has two valence electrons, and chlorine can accept one electron in its outer shell.

The number of electrons that an atom of an element has in its outermost shell determines the chemical formula of the compounds formed by atoms such elements.

Magnesium is in group 2, as such it has two electrons in its outermost shell while chlorine in group 17 only accepts one electron in its outermost shell. This one electron will give chlorine an inert gas configuration while the loss of two electrons give magnesium an inert gas configuration.

Therefore; The compound MgCl2 is formed in the ratio of 1:2 because Magnesium has two valence electrons, and chlorine can accept one electron in its outer shell.
