Properties
The unequal sharing of electrons, resulting in oppositely charges ends (poles) of a molecule.
What is polarity?
Two or more elements, chemically combined in a specific ratio.
What is a chemical compound?
A substance that donates H+ when in solution, has a sharp taste and is able to dissolve metals.
What is an acid?
The end of the water molecule that attracts the most electrons, causing it to have a partial negative charge.
What is the Oxygen atom?
What are valence electrons?
A substance that dissociates in water to form hydroxide ions (OH-), has a slippery feel and a bitter taste.
What is a base?
The end of the water molecule that attracts the LEAST electrons, causing it to have a partial positive charge.
What is the Hydrogen end?
An atom of an element with a different number neutrons.
What is an isotope?
A substance with a pH of less than 7 on the pH scale.
What is an acid?
The property of water that allows it to neutralize acids and bases.
What is "Buffering ability"?
the property of water that allows it to absorb a large amount of heat energy before its temperature significantly increases, making it resistant to rapid temperature changes
What is "high heat capacity" or "specific heat".
A substance that will NOT dissolve in water due to EVENLY shared electrons, resulting in little to no electronegativity.
What is a proton?
A substance with a pH of greater than 7 on the pH scale.
What is a base?
A substance with a pH of 4.3 is more ______ than a substance with a pH of 4.7.
What is acidic?
This property of water allows ice to float on the surface, creating an insulating layer that protects aquatic life below from extreme cold temperatures, ensuring their survival during winter months
What is water's decrease in density as if freezes?
Water is sometime referred to as the ____________________ due to its ability to dissolve many substances.
What is the Universal Solvent?
The type of bond that involves sharing of electrons between atoms.
What is covalent?
What is Potential Hydrogen?
