Acids And Bases Flashcards
Titration
A titration is a method of analysis that will allow you to determine the precise endpoint of a reaction and therefore the precise quantity of reactant in the titration flask. A buret is used to deliver the second reactant to the flask and an indicator or pH Meter is used to detect the endpoint of the reaction.
tests for Hydrogen and Carbon Dioxide
A lighted wooden splint goes out in a test tube of carbon dioxide but this happens with other gases, too. It is better to bubble the test gas through limewater - calcium hydroxide solution.
Carbon dioxide turns limewater cloudy white. A lighted wooden splint makes a popping sound in a test tube of hydrogen.
Acid + base =
salt + water
Acid+metal carbonate=
salt+water+carbon dioxide
Acid+metal=
salt+hydrogen
What is acid rain
Acid rain is caused by nitrogen oxides and sulfur dioxide produced by both natural processes and the combustion of fossil fuels. Eventually, these oxides react with oxygen and water to give nitric acid and sulfuric acid.
techniques of soluble salt preparation
Add excess insoluble carbonate or metal to the dilute acid and filter and remove the residue. Evaporate the filtrate to form a saturated solution, then use crytallization to obtain crystals.
Making acid rain formulas
CO2+H2O=H2CO3
SO2+H2O=H2SO3
2NO2+H2O=HNO2+HNO3
Soluble compounds
Nitrates
Chlorides
Sulfates
Insoluble compounds
Carbonates
Hydroxides
Sulfides
Oxides
Describe what a scrubber does
When the exhaust gas passes through the scrubber a spray mixture of limestone and water reacts with the SO2, which is then removed before released to the atmosphere.
What happens in a catalytic converter
Use a platinum and rhodium catalyst with a larger surface area . This increases the rate of reaction of carbon monoxide and unburnt fuel from exhaust gases with oxygen from the air. Producing carbon dioxide and water
