Are weak acids able to act as chemical buffering systems for the body because they partially dissociate?
Yes, they are able but in certain cases.
What is the proper definition of acids?
a. Any of a class of substances whose aqueous solutions are characterized by a sour taste, the ability to turn blue litmus red, and the ability to react with bases and certain metals to form salts.b. A substance that yields hydrogen ions when dissolved in water.c. A substance that can act as a proton donor.d. A substance that can accept a pair of electrons to form a covalent bond.
Do acids accept a pair of electrons?
according to Lewis theory acids act as electron pair acceptors bases act as electron pair donors
Are all substances either acidic or basic?
No. Many substances will act as neither acids nor basic. There are also amphoteric substances, which can act as both acids and bases depending on the circumstances.
What functional group is highly polar and may act as a weak acid?
Carboxyl groups are highly polar and can act as weak acids.
What gas evolved when acids act on certain metals?
Hydrogen gas, H2

What does rcra stand for?
It stands for the Resource Conservation and Recovery Act. It determined acceptable levels for certain metals in our environment, and was written back in 1976. It specifically monitors levels of 8 different metals that have special environmental concerns. Those metals, called the RCRA-8 metals, are arsenic, barium, cadmium, chromium, lead, mercury, selenium and silver.
Do bases act vigorously with many metals?
no
