Water Basics
This type of bond holds the hydrogen and oxygen atoms together inside one water molecule.
Covalent bond
The substance that does the dissolving in a solution.
Solvent
This property helps lakes and oceans resist rapid temperature changes.
A substance with a pH greater than 7 is classified as this.
Base
The slightly negative end of a water molecule is found near this atom.
Oxygen
Water molecules stick to each other because of this property.
Cohesion
A solution that looks the same throughout is called this type of mixture
Homogeneous mixture
Water sticking to other materials, like glass or plant cells, is called this.
Adhesion
Pure water has this pH value.
7
When salt dissolves in water, the water molecules surround the ions because water is this type of molecule.
Polar
This property allows water to climb up a plant stem against gravity.
Capillary action
The amount of solute dissolved compared to the amount of solvent describes this.
Concentration
In plants, water moves upward through narrow tubes using this combined effect.
Capillary action
Lemon juice with a pH of 3 would be classified as this.
Acid
A student adds more and more sugar to water until no more dissolves. The solution has reached this point.
Saturation
Water can dissolve many ionic and polar substances because of this characteristic.
Polarity
Sugar disappearing evenly in tea is an example of this process.
Dissolving
This water property allows some insects to walk across ponds without sinking.
Surface tension
A substance with a pH of 11 has more of these ions than hydrogen ions.
hydroxide
A beaker with 5 g of salt in 50 mL of water is more concentrated than one with 5 g in 200 mL because it has this.
More solute per amount of solvent
This force exists between different water molecules, not within a single molecule.
Hydrogen bond
The maximum amount of solute that can dissolve in a solvent is known as this.
Solubility
Sweating cools the human body because water requires lots of energy for this phase change.
Evaporation
Moving from pH 5 to pH 3 means the solution became this.
more acidic
This is the reason ice floats on liquid water.
Solid water is less dense than liquid water
