Ans :
Strong acids are the ones that readily ionise and give off their protons , whereas the weak acids are the ones that do not dissociate or partially dissociate giving off their protons.
bases are the ones that give off their hydroxide ions.
Soluble salts are easily soluble in water whereas insoluble salts are not.
So here :
HF is weak acid
NaClO4 is soluble salt
H2SO4 is strong acid
NaOH is strong base
PbI2 and Cr3(PO4)3 are insoluble salts
or a soluble or insoluble salt 4, Classify as strong or weak acid or HF NaCIO4...

HF is a weak acid (a monoprotic one). When HF is titrated with a strong base (like NaOH), it will eventually reach an equivalence point where exactly all of the HF has been reacted with exactly the needed amount of NaOH. What will the pH be when HF reaches equivalence point? (Hint: think about what products will be present and whether they are weak acids, weak bases or neutral...) pH will be 7.0 pH will be greater than 7.0 pH...
