A
pH
5
Q

ions
6
Q
what happens when acids dissolve into water?
A
they donate H+ ions into the water (this is what makes the solution acidic)
7
Q
what happens when alkalis dissolve into water?
A
they donate OH- ions into the water (this is what makes the solution alkaline
8
Q
what happens when bases dissolve into water?
A
they accept H+ ions from the H2O molecules
- but when an H2O molecule loses an H+ ion, what’s left over is a OH- ion
- these ions cause the solution to be labelled alkaline
