What is the ph of a 3.9* 10^-8 m oh- solution

pH = 6.59

Explanation:

pOH = -log(3.9 x 10^-8) = 7.41

pH = 14 - pOH = 14 - 7.41 = 6.59

For the most part, non-metals (excluding Nobel gases) are the most likely to form covalent bonds. Pure covalent bonds are formed between atoms with the same electronegativity, ie. they are trying to hold on to the electrons in the bond with the same strength.
