What feature of the bond between hydrogen and oxygen is most important in explaining how water can act as a powerful solvent?
The electronegativity difference between oxygen and hydrogen is quite large, which means that bond possess a high polarity. This enables water (which has two O-H bonds) to "surround" similar covalent compounds and dissociate many ionic compounds.
Compounds with both ionic and covalent bonds contain this type if ion?
Compounds with both ionic and covalent bonds contain polyatomic ions. These ions consist of more than one atom covalently bonded together and carry a net charge, making them act as single units in ionic compounds.
Is water is a solute?
no water is a solvent
Why does the electrical conductivity of ionic compounds change when they are dissolved in water?
Electric current is the flow of charged particles. When ionic crystals disolve in water, the bonds between ions are broken. As a result, the ions are free to move about, and the solution conducts current. Likewise, when an ionic compound melts, the ions are able to move freely, and the liquid conducts current. In contrast, ionic compounds in solid form do not conduct current well. The ions in the solid crystal are tightly bound to each other and cannot move from place to place. If charged particles cannot move, there is no current.
What part of air is the solvent and why?
Water vapor would be the solvent. Water alone is a good solvent.
Do ionic compounds act as the solute or solvent?
generally the solute
Is hydrogen chloride a solvent?
Hydrogen chloride is a polar compound. Therefore it can act as a solvent to particular polar compounds.

Does waters polarity help it act as a universal solvent?
Yes, water's polarity allows it to form hydrogen bonds with other molecules, making it an excellent solvent for a wide range of substances. The positive and negative charges on water molecules can surround and break apart solute molecules, allowing them to dissolve in the water.
Which experiment best shows water's ability to act as a solvent?
A simple experiment that demonstrates water's ability to act as a solvent is dissolving sugar or salt in water. You can observe the solid substance disappearing as it mixes with water, showing that water can dissolve a variety of solutes due to its polar nature.
When you mix water with sugar does the sugar act as a solvent?
No, the sugar is the solute and the water is the solvent.
How does water act in most solutions?
As the solvent.

Is water a solvent in air liquid sterling silver or saline?
Water can act as a solvent in all three cases. In air, water vapor dissolved in the air can act as a solvent for certain gases. In liquid sterling silver, water can dissolve small amounts of silver ions. In saline solution, water is the solvent that dissolves the salt (sodium chloride) into ions.

no water is a solvent
