give the formula of hydrochloric acid + type of salt it forms

Back (Answer)

• HCl • chloride

#2
Front (Question)

give the formula of sulfuric acid + type of salt it forms

Back (Answer)

• H2SO4 • sulfide

#3
Front (Question)

Back (Answer)

• CH3COOH • ethanoate

#5
Front (Question)

give the formula of sodium hydroxide

Back (Answer)

NaOH

#6
Front (Question)

give the formula of potassium hydroxide

Back (Answer)

KOH

#7
Front (Question)

give the formula of ammonia

Back (Answer)

NH3

#8
Front (Question)

what differentiates an acid from an alkali

Back (Answer)

• acids release H+ ions in aqueous solutions as protons • alkalis release OH- ions in aqueous solutions

#9
Front (Question)

what is the difference between a strong and weak acid

Back (Answer)

• a strong acid releases all of its hydrogen atoms into the solution and completely dissociates in aqueous solution • weak acid partially dissociates in aqueous solutions and only releases small amounts of hydrogen atoms

#10
Front (Question)

define a base

Back (Answer)

• base neutralises an acid to form a salt

#11
Front (Question)

define an alkali

Back (Answer)

• a base that dissolves in water releasing hydroxide ions (OH-) into the solution

#12
Front (Question)

define neutralisation

Back (Answer)

• in neutralisation , the H+ ions from an acid react with a base to form a salt + neutral water > the H+ ions from acid are replaced by metal or ammonium ions from the base

#13
Front (Question)

acid + alkali —>

Back (Answer)

acid + alkali —> salt + water

#14
Front (Question)

acid + metal oxide —>

Back (Answer)

acid + metal oxide —> salt + water

#15
Front (Question)

acid + metal hydroxide —>

Back (Answer)

acid + metal hydroxide —> salt + water

#16
Front (Question)

acid + metal carbonate —>

Back (Answer)

acid + metal carbonate —> salt + water + carbon dioxide

#17
Front (Question)

what is a titration

Back (Answer)

• a technique used to accurately measure the volume of one solution that reacts exactly with another solution

#18
Front (Question)

what can titrations be used for

Back (Answer)

• finding concentration of a solution • identification of unknown chemicals • finding the purity of a substance

#19
Front (Question)

what is a standard solution

Back (Answer)

• a solution of known concentration > a volumetric flask is used to make up a standard solution very accurately

#20
Front (Question)

what is an acid-base titration

Back (Answer)

• when a solution of an acid is titred against a solution of a base using a pipette and burette

#21
Front (Question)

what is the end point of a titration identified by

Back (Answer)

• an indicator
