11.2 A closer look at acids and alkalis Flashcards
Acids produce
Hydrogen ions
how acid reacts in the water
in water the molecules break up and disassociate
example of HCl when dissolves in water
in water HCl will break up to hydrogen (H+) ion and (Cl-)chloride
HCl —> H+ + CL-
how acids conduct electricity
As solution contains ions they conduct electricity
what are the strong acids
they have high conductivity but low pH example: hydrochloric acid and sulfuric avid and nitric acid
what are the weak acids
weak acids have low conductivity with high Ph examples: mathanoic acid and ethanoic acid and citric acid
difference between strong and weak acids
in solutions of strong acids, all the molecule’s become ions. in solution of weak acids, only some do
why are strong acids conductors
strong acids conduct better because there are more ion present.
why are weak acids have weak conductivities
there are few hydrogen ions present only
what is the acid available in car battery
sulfuric acid
which ion are produced by alkaline
Hydroxide example: sodium hydroxide produces sodium ion and hydroxide ion
NaOH –> Na+ + OH-
what are the strong alkaline
strong alkaline has high pH value and high conductivity. example: sodium hydroxide(NaOH) potassium hydroxide (KOH)
what are the weak alkaline
they have low pH and low conductivity exmaple: ammonia solution (NH3)
why weak alkaline are weak conductors
they make fewer hydroxide ions
why sodium hydroxide is a stronger conductor than ammonia acid
sodium hydroxide make more hydroxide ion than ammonium acid
