Acids And Basis Flashcards
Ph scale
Numbered 1-14
Under 7 = acid
Over 7= base
7=neutral
2 lab acids
Sulphuric acid -H2SO4
Hydrochloric acid - HCL
2 lab bases
Calcium carbonate- CACO3
Sodium hydroxide- NAOH
Blue litmus paper
Turns red when there is an acid
Red litmus paper
Turns blue when there is a base
Ph scale used for
To measure how acidic or basic something is
Neutralisation
Putting an acid and a base together to make it neutral
Acid + base = salt and water
Example 1.hydrochloric acid +sodium hydroxide =sodium chloride +water
Acid +________=salt+__________+____________
Acid + carbonate= salt + water + carbon dioxide
Titration
A method of finding out the exact amount of acid required to just neutralise a certain volume of a base
How to titration hydrochloric acid against sodium hydroxide
hydrochloric acid + sodium hydroxide = sodium chloride + water
HCL+NAOH=NACL+H2O
Reaction between zinc and hydrochloric acid and test for hydrogen
Zinc +hydrochloric acid = zinc chloride + hydrogen
ZN+2HCL=ZNCL+H2
