Properties of water Flashcards
Water having partial positive and negative charges due to unequal sharing of electrons is known as:
Polarity
The (-) oxygen of one water molecule attracts the (+) hydrogen of another water molecule, allowing them to connect is known as:
Hydrogen bond
Oxygen has a _______ charge
Negative
Hydrogen has a ________ charge
Positive
________ is when water molecule stick together because of hydrogen bonding in formed surface tension. The molecule typically form a droplet.
Cohesion
A special form of cohesion that causes the surface of water to resist rupture and allow bugs to walk across is known as __________ __________
Surface tension
_________ is known as water molecule sticking to something other than water due to attraction of charges. Example: keeps the droplets of water stuck to the plant.
Adhesion
Another name for “ tubes inside plants that transports water” is: ______
Xylem
_________ _________ is known as a tendency of water to move along the surface of a substance due to adhesion. Water molecules “ pull” each other up.
Capillary action
Frozen water (ice) always ________ because it is less dense as a solid
Floats
______ ______ _______ takes a lot of energy to raise the temperature of a certain amount of water
High specific heat
Water is known to be a _________ solvent because it can dissolve many polar ionic substance because of the partial charges within the water molecule
Universal
_________ usually liquid substance capable of dissolving or dispersing one or more other substance
Solvent
________ is the minor component in a solution, dissolved in the solvent
Solute
Salt and sugar can dissolve in water (water loving), this means they are ____________
Hydrophilic
Oil cannot dissolve in water (water fearing), this means oil is ____________
Hydrophobic
__________ it’s typically a higher number on the pH scale, also known as “basic”
Alkaline
__________ is typically number seven on the pH scale, not acidic, but not basic.
Neutral
________ is typically a lower number on the pH scale
Acidic
Water is less _______ as a solid. This is why ice floats.
Dense
Oil is what kind of polar
Non-polar
Water is what polar
Polar
