thank youfor june 2005 , to neutralise the same conc and vol of calcium hydroxide , less vol of M was used so it must be more concentrated!
june 08 sol A is more conc and stronger than sol BJune 2005, Question 4, b (iii)
June 2008, Question 4, e (iii)
how should I know which solution is more concentrated?
it's so confusing
yeah!and if it's a neutralisation reaction, the smaller volume is more concentrated, right?
same hereDoes anyone know how to do the last question on every past paper, i always have problems with it. Is there any topic to revise or anything to study for these type of questions from?
u can understand that by reading the question for example if they mention in the question that its ammonium chloride n give the test for sulphate so in the observation u'll write "no change/reaction"I have the same doubt ^^
& how do we know for the cation & anion test that the reaction wont take place or /no change ??
okay! thanksu can understand that by reading the question for example if they mention in the question that its ammonium chloride n give the test for sulphate so in the observation u'll write "no change/reaction"
