Acids and Bases Flashcards
what do we use to define if a substance is acidic or alkaline
We use a pH scale
where are acids on the pH scale
0-6
where are alkalines on the pH scale
8-14
what is neutral on the pH scale
7
most acids have what in their formulas
An H at the beginning or at the end
what are acids in terms of protons
they are protons donors which means they release H+
what are bases in terms of protons
they are proton acceptors
what else are bases
metal oxides, metal hydroxides
what are alkalis
they are bases which dissolve in water
what alkalis produce
hydroxide ions
how do you tell a solution is a base
metal oxide = base
metal hydroxide = base
how do you tell a solution is a salt
metal nitrate = salt
metal sulfate = salt
metal chloride = salt
Acid + Metal oxide/hydroxide —>
salt + water
Acid + Metal —>
Salt + Hydrogen
Acid + metal carbonate —>
Salt + Water + Carbon dioxide
