as one goes down the periodic table through the halogen group, the hydro halides they form demonstrate STRONGER ACIDITY
Most acidic is Iodine, forming HI.
63
New cards
least acidic is fluorine (F) forming HF
64
New cards
in order of decreasing acid strength, hydro halides can be arranged as follows:
HI \> HBr \> HCl \>HF

this graph approximates the pH curve for titration of weak acid (analyte) with strong base (titrant)
68
New cards
There is a sharp rise in pH after certain amount of strong base is adeed
the stoichiometric point S occurs on the basic side of pH \= 7.
69
New cards
This is because the strong base causes the solution to be basic after neutralizing the weak acid
