Acetone major species present when dissolved in water (CH3)2CO

Hydrogen bonding

Explanation:

Acetone major species present when dissolved in water is called hydrogen boding. these occurs when, the acetone and water as the oxygen of acetone's cabonyl bond with the O-H of water.

Such presence of hydrogen bonding would helps the ability of molecules of two types to be miscible together

it is a good conductor

explanation:

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.
