1. Such as in the interior of giant planets, it is argued that water exists as ionic water in which the molecules break down into hydrogen and oxygen ions. What conditions are required for water to exist in its ionic form? a. High temperature, low pressure b. Low temperature, low pressure c. High temperature, high pressure d. Low temperature, high pressure 2. Water is a polar molecule with an electrical dipole moment. The polarity of water is due to a. Higher electronegativity of oxygen atoms b. Hydrogen atoms are slightly positive c. Oxygen carries a slight negative charge d. All of the above 3. A good clean potable water will give dissolved oxygen value close to the theoretical value for the saturated solution of oxygen in water. a. True b. False c. Sometimes d. Insufficient data
