Why are salt and sugar both able to dissolve in water, even though the solutes have different types of chemical bonding?

See explanation

Explanation:

A substance is only soluble in water if it is composed of ions or polar groups which are capable of interaction with water.

Salt is composed of ions which are easily solvated by the dipoles of water molecule. Sucrose is composed of polar groups capable of interaction with water. This accounts for the solubility of sucrose (sugar) in water. Sugar is a covalent molecule but is composed of polar groups while salt is composed of ionic bonds.

Hence salt and sugar are both soluble in water for the reasons described above.

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.
