30 points which of the following are properties of ionic compounds? i. very soluble in water ii. consist of molecules iii. low melting points iv. exist as crystalline solidsi & & ivii & & iv

Answer : The correct option is, I & IV

Explanation :

Ionic compound : Ionic compound are the compounds which are made up of ions. These ions are held together by the electrostatic force of attraction between the oppositely charged ions.

Properties of ionic compounds :

Therefore, the option (I) and (IV) are the properties of ionic compounds.

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.
