Front (Question)

Acids means

Back (Answer)

Sour

Front (Question)

Bases includes

Back (Answer)

Metallic oxides and Hydroxides

Front (Question)

How are salts formed?

Back (Answer)

Replacement of hydrogen ions of corresponding acids of metallic ions.

Front (Question)

Define an acid? (Simple)

Back (Answer)

• When dissolved in water -> hydronium ion (H3O+) 2. That should be the only + ve ions.

Front (Question)

Define a base? (Simple)

Back (Answer)

• Reacts with hydronium ions of acid. 2. Gives Salt and Water only.

Front (Question)

Classify the following as Alkalis or Insoluble bases: • ZnO • PbO • NaOH • Ca(OH)2 • NH4(OH) • Fe(OH)2 • CuO • Cu(OH)2

Back (Answer)

5, 4, 2 -> Alkali 1, 6, 3, 7 and 9 -> Insoluble bases

Front (Question)

5 Basis for classificaton

Back (Answer)

• Source of acids • Molecular comparison of acids • Basis of strength • Basis of concentration • Basis of acidity and basicity

Front (Question)

Source of acids ->

Back (Answer)

• Organic’ 2. Inorganic -> Aka Mineral acids

Front (Question)

Molecular comparison ->

Back (Answer)

• Hydraciods -> Shouldnt have Oxygen 2. Oxyacids

#10

Front (Question)

Strength of Acids depends on

Back (Answer)

Concentration of Hydronium Ions present in aqueaous solution.

#11

Front (Question)

Strenght of Alkali depends on

Back (Answer)

Concentration of Hydroxyl Ions present in an aqueous solution.

#12

Front (Question)

Strong acids:

Back (Answer)

So No class Brings In H2SO4 HNO3 HCl Hbr HI HClO3 HClO4

#13

Front (Question)

Which contains solute molecules in addition to water molecules?

Back (Answer)

Strong alkali

#14

Front (Question)

Define a strong acids

Back (Answer)

Disasosciates almost completely in aq solution -> High conc. of H+ ions.

#15

Front (Question)

Define a strong Base

Back (Answer)

Disasosciates almost completely in aq solution -> High conc. of OH- ions.

#16

Front (Question)

Strong acids and bases contains _______.

Back (Answer)

Almost only ions.

#17

Front (Question)

Weak acids and bases contains ________.

Back (Answer)

Contains molecules and Ions.

#18

Front (Question)

Define weak acids

Back (Answer)

Disasosciates partially in aq solution -> Low conc. of H+ ions.

#19

Front (Question)

Define weak alkali

Back (Answer)

Disasosciates partially in aq solution -> Low conc. of OH- ions.

#20

Front (Question)

Concentration:

Back (Answer)

Concentratedd and Dilute

#21

Front (Question)

Concentration of more than 1 mol/litre

Back (Answer)

Concentrated

#22

Front (Question)

Concentration of less than 1 mol/litre

Back (Answer)

Dilute

#23

Front (Question)

Define Dilute/Concentrated acid/alkali

Back (Answer)

Relatively Low/high % of acid/alkali in aq solution. different from strength

#24

Front (Question)

Basicity -> It is a whole number value.

Back (Answer)

No of H ions -> Produced in aq solution/molecule. No of OH- ions -> With which one molecule of acids can combine.
