AIM• To find out what happens when combinations of water ,sodium bicarbonate and tartaric acid are mixed.
PREDICTION• Bottle 1: I predicted that the powders wouldn’t react because there’s no water in the bottle.• Bottle 2: It would sink to the bottom of the bottle.• Bottle 3: same as bottle 2.• Bottle 4: I thought it was going to blow the balloon up.
STEPS USED1.First I got the equipment I needed.2.Then I labelled the balloons and the bottles and then put the powders in the balloons and water in the bottles.3.I then tipped all the different powders into the bottles one by one.4.Some reacted and some didn’t.
BOTTLE 1The two powders fell to the bottom of thebottle and the balloon went up a little bit withair.
BOTTLE 2The powder sunk to the bottom and when Imixed the powders it nearly dissolved.
BOTTLE 3When I put the powder in the bottle it sunkto the bottom and when I mixed it, thewater bubbled a little bit and nearlydissolved the powder.
BOTTLE 4When I put the powders in the bottle, thewater fizzed up and blew the balloon up, andthe water started to over flow.
I believe that bubbles are little pockets of airthat appear when the sodium bicarbonateand the tartaric acid mix with the water.The bubbles only appear when the twopowders mix with water. I think the balloononly inflated when the bubbles popped andair got pushed into the balloon. I think if youmix bottles 2 & 3 together that it will producethe same reaction as bottle 4. In conclusion,I wouldn’t do anything differently.
