Flashcards do conjunto (12)
- 1Strong acidCompletely dissociates
Gives up all its H atoms as H+
HCl -> H+ + Cl-
The chlorine keeps the electron - 2Why is H+ a proton?As the hydrogen atom has lost its electron and so effectively consists of just a single proton
- 3Weak acidOnly gives up a proportion of its H atoms as H+
- 4Why is ethanoic acid weak?As it only gives up the hydrogen from its COOH group, proffering just a meager proportion of its hydrogens
- 5Why is the hydroxide ion negative?As the H atom absconds, it leaves behind its electron to the mother O-H complex
- 6What is a baseBases neutralise acids to form a salt
Mop up loose charged atoms - 7Alkalisoluble base that dissolves in water to release a hydroxide ion.
- 8What replaces the H+ ion?Metal or NH4+ ions from the base.
- 9Sulfuric acidOnly one of its H+ ions is a strong acid
SO4- readily reassociates with protons to form HSO4- and so is weak. - 10What is the typical burette measurement read to?+/- 0.05cm3
So reading ALWAYS has 2 decimal places - 11What is the criteria for concordant results?Agreeing to within 0.10cm3 of each other
- 12how do you work out mean titre?add + divide by 'n'.
