bleach is
an acid
a base
if you add an acid to a base what will happen?
BOOM
it will neutralize (the OH- from the base reacts with H+ from the acid to make water)
it wont mix
The H+ ions acids give off are called...
acidic protons
basic protons
The H+ ions acids give off are called acidic protons because hydrogen is a proton and an electron and when it losses its electron there is only a proton left.
True
False
A Hydrogen atom has one proton and one neutron.
true
false
