Front (Question)

What is the relationship between strength of an acid and dissociation?

Back (Answer)

The weaker the acid the lower the proportion of the acid is dissociated

Front (Question)

What is the relationship between strength of an acid and H+ ions?

Back (Answer)

The weaker the acid the lower the CONCENTRATION of H+ ions in the solution

Front (Question)

Explain why in the following reaction the hydroxide ion is acting as a base: NaOH + HCl —-> NaCl + H2O

Back (Answer)

The hydroxide ion has accepted a proton

Front (Question)

What is produced when a water soluble metal oxide reacts with water?

Back (Answer)

An aqueous hydroxide is formed

Front (Question)

What is produced when a water insoluble oxide reacts with water?

Back (Answer)

No reaction

Front (Question)

What is produced when a water insoluble oxide reacts with acids?

Back (Answer)

Water and a salt

Front (Question)

What are the 3 types of bases?

Back (Answer)

• metal hydroxides • metal oxides • ammonia

Front (Question)

How is ammonia able to act as a base?

Back (Answer)

The lone pair on the nitrogen atom is able to form a bond with a H+ ion

Front (Question)

What is the symbol equation (including state symbols) for the reaction of ammonia with water?

Back (Answer)

NH3 (aq) + H2O (aq) —> NH4+(aq) + OH- (aq)

#10

Front (Question)

Give the equation for water acting as a base Give the name of the ion produced

Back (Answer)

H+ + H2O —> H3O+ This produces a hydronium ion

#11

Front (Question)

Give the names and formulae of the 3 most common alkalis

Back (Answer)

Sodium hydroxide, NaOH Potassium hydroxide, KOH AQUEOUS ammonia NH3 (aq)

#12

Front (Question)

Explain why ammonia is an alkali

Back (Answer)

When in aqueous solution it produces ammonium ions and hydroxide ions. It has accepted a proton so is a base and because it releases OH- ions in aqueous solution it is an alkali

#13

Front (Question)

Is it true that all alkalis are bases but not all bases are alkalis?

Back (Answer)

yes

#14

Front (Question)

Acid + reactive metal —> ?

Back (Answer)

salt + hydrogen

#15

Front (Question)

Acid + metal hydroxide —> ?

Back (Answer)

salt + water

#16

Front (Question)

Acid + metal oxide —>?

Back (Answer)

Salt + water

#17

Front (Question)

Acid + metal carbonate —> ?

Back (Answer)

Salt + CO2 + water

#18

Front (Question)

What dictates what salt is formed?

Back (Answer)

The acid, e.g. HCl forms chlorides

#19

Front (Question)

When are Cl-, I-, and Br- not soluble?

Back (Answer)

When combined with Ag+, Pb2+, or Hg2+

#20

Front (Question)

When are sulfate compounds insoluble?

Back (Answer)

When combined with Ag+, Pb2+, Ca2+, Sr2+, Ba2+
