:: chem prac ::
m blogging now cos steff asked me to blog... not really, but i dun feel like studying anyway...
chem prac today was relatively easy, at least, the titration was... you just had to calculate the concentration of the acid used... what stunned me was the finding out of the acid... both the nitrate and the chloride test tested positive, but the sulphate test tested negative... then i blur and i put down nitric acid... but then later i redo the test again and the nitrate was negative... so the acid was hydrochloric acid...
the QA part was scary... both my solution S dissolved in excess of NaOH and NH4.H20... so i put it down as ZN... but alot of my friends got AL... then i heard that the NYGH teachers said that it was ZN, so i m rather relieved...
oh ya... that david kwang said that the extension question was going to be difficult and it was the deciding factor... i got scared out of my wits la... but then it was just a simple question of designing an experiment to determine the concentration of the acid R... so easy... i think the deciding factor was the QA... whether it is ZN or AL...
nonetheless... i have prayed and i will leave it all to the Lord to settle it for me...
