Science acids and bases
how does an acid react with the metals magnesium,zinc and iron?
its corrosive to metals and hydrogen gas is produced
hydroxide ion
polyatomic ion made of oxygen and hydrogen
what color does an acid turn litmus paper?
red
what does an acid taste like?
sour
what is the difference between a strong acid and a weak acid?
the difference between a strong acid and a weak acid is in a strong acid,most of the molecules break up into ions in a solution. A weak acid has fewer molecules and they break up into ions.
what is the difference between a strong base and a weak base?
the difference between a strong base and a weak base is a strong base breaks up ions into a solution and a weak base breaks up molecules into ions
what is the pH of a neutral solution?
the pH of a neutral solution is 7
what are the products formed when a base reacts with an acid?
the products that are formed when a base reacts with an acid is water and salt.
which solution has a greater concentration of hydrogen (H plus),a solution with a pH of 3 or one with a pH of 7?
the solution with a pH of 3 has a greater concentration of hydrogen ions. As a pH values decrease the concentration of hydrogen ions increases.
if a substance reacts with a metal to produce hydrogen gas,what may you infer about the substance?
the substance is an acid.
acid rain
a problem caused by gases that are released into the air as pollutants
neutralization
a reaction between an acid and a base
pH scale
a series of numbers that indicates the concentration of hydrogen ions in a solution
what does corrosive mean?
a substance that can eat away at certain materials.
what is an indicator?
a substance that turns different colors in an acid or base.
a substance with a pH in the numbers 0123456 in this range are
acids
salt
an ionic compound that can form from the reaction of an acid with a base
a substance with a pH in the numbers 8,9,10,11,12,13,14 in this range are
bases
why do you think bases are often described as the "opposites" of acids?
bases are bitter rather than sour. bases turn litmus paper blue rather than red. bases do not react with the metals and carbonates the way acids do.
what does a base taste like?
bitter
what color does a base turn litmus paper?
blue
how does an acid react with carbonates?
carbon dioxide gas is made
how does a base react with carbonates?
does not react
how does a base react with the metals magnesium,zinc and iron?
does not react
in water acids form?
hydrogen ions
in water bases form?
hydroxide ions
