Use the list to answer the question. potassium, Group 1
calcium, Group 2
iodine, Group 17
neon, Group 18

Which two elements in the list would bond together based on their ionic charges?
If you could describe to me how that would be appreciated

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
