Why is H+ a Proton - correct answer Because hydrogen is just one proton and one electron. Take away the electron and you're left with H+. Define Alkali - correct answer A type of base which dissolves in water to form OH- ions (a soluble base). What is a Monobasic Acid and Give an Example of One - correct answer A monobasic acid e.g. HCl is an acid which ...

Test for carbonates - correct answer - add dilute HCL - it makes carbon dioxide test for carbon dioxide by bubbling it through lime water Test for ammonium ions - correct answer -add sodium hydroxide -warm the mixture -hover damp red litmus paper over it , if it turns blue the ions are present Test for sulphate ionz (SO4 2-) - correct answer - add dilute HCL - then add BaCl2 - BaSO4 is made which is insoluble in water so a white precipitate will be formed Test for Halides (Cl-,...
