are acid base reactions exothermic or endothermic?

Answer 10

they are exothermic proton transfer reactions

Question 11

limitations of bronsted lowry?

Answer 11

cannot explain acidity/ basicity of substances that do not donate / accept protons

Question 12

example of bronsted lowry limitation

Answer 12

BF3 is acidic but cannot donate protoms

Question 13

difference between amphiprotic and amphoteric ?

Answer 13

amphiprotic - can donate / accept protons

amphoteric - can act as an acid/base
