coursework - unknown acid: tests - PLEASE HELP!
can someone PLEASE help me?!
as my username suggests...i am thick when it comes to Chemistry...so i really need some help with my coursework.
basically i need to know the 2 chemical tests (without use of indicators) to test an unknown aqueous substance to see if it is an acid.
1 test is CO2 emission in Limewater.
2 test is H emission from acid + metal.
thing is...i don't know how you actually DO these tests...or anything about the H+ ions which cause the gas emissions.
PLEASE PLEASE PLEASE can someone help me out?
i need to know about the donating and receiving of H+ ions AND the apparatus needed and the methods of both the 2 tests.
Sorry...should have said...the unknown acid formula is MHSO4 (where M is either sodium or potassium).
