B- is bronsted and Lowry's theory. answers D.simonkey said:Whats the answer to question 8?? Is it really d?? But i put b =[
According to the Arrhenius theory of acids and bases, an acid is a substance that
(a) tastes sour
(b) is capable of donating a hydrogen ion
(c) can accept a pair of electrons to form a co-ordinate covalent nob.
(d) increases the concentration of ions in an aqueous solution
Nah its D. Arrhenius theory is that an acid ionises into H+ ions in solution, so it would increase the concentration of hydrogen ions. It cant be B because thats Bronsted Lowry theory - An acid donates a proton. And a proton is a hydrogen ion.simonkey said:Question 8 again.... ermm.
i still reckon (b) is the answer cos (d) is a bit wrong.
If you have really concentrated acid and u add dilute acid, u can decrease the concentration of hydrogen ions. Because concentration is moles/volume.
-I was put off by "donating a hydrogen ion" cos u always use donating when talking about Bronsted and Lowry, but its right, isnt it??
(I HATE DUMB PEOPLE)
from the papers ive done, they like always ask the arrhenius, dacy, laviosier, BL thing. But i havent done that many papers so loltau281290 said:There was a similar question on Q8 before, i guess lots of ppl fail it so they asked us again this time.
