Front (Question)

type of bonding in acids & bases & salts

Back (Answer)

acid - covalent - shared pair of e btw non-metals; attraction of protons & e base - ionic - transfer of e btw metal & non- metal; electrostatic force of attraction btw (+) & (-) ions salts - ionic

Front (Question)

acidic or basic: -metal oxides -non- metal oxides

Back (Answer)

-basic -acidic

Front (Question)

what colour does litmus paper turn under acid & alkaline (need to be soluble)

Back (Answer)

-acid - red base - blue

Front (Question)

3 kinds of indicators

Back (Answer)

-universal indicator -methyl orange solution -phenolphthalein

Front (Question)

base colour for -universal indicator -methyl orange solution -phenolphthalein

Back (Answer)

-universal indicator - blue -methyl orange solution - yellow -phenolphthalein - dark pink

Front (Question)

acid colour for -universal indicator -methyl orange solution -phenolphthalein

Back (Answer)

-universal indicator - red -methyl orange solution - red -phenolphthalein - colourless

Front (Question)

3 common acids/ strong acids

Back (Answer)

-hydrochloric acid HCL -sulfuric acid H2SO4 -nitric acid HNO3

Front (Question)

3 common bases/ weak acids

Back (Answer)

-Sodium hydroxide NaOH -Potassium hydroxide KOH -Calcium hydroxide Ca (OH)2 -eg. Magnesium hydroxide

Front (Question)

2 weak acid & base

Back (Answer)

acid: -ethanoic acid -citric acid base: -ammonia hydroxide

#10

Front (Question)

what is pH

Back (Answer)

-measure of acidity -1 pH change = 10^1 times [H+ ions]

#11

Front (Question)

define strength

Back (Answer)

-how much compound dissociated in a liquid

#12

Front (Question)

difference btw strong & weak acids/bases

Back (Answer)

-strong: dissociated fully in water eg. HCl -> H+, Cl- -weak: dissociated partially in water

#13

Front (Question)

define concentration

Back (Answer)

amount of compounds in a given volume

#14

Front (Question)

formula for concentration

Back (Answer)

-mass/ volume - g / (d/c)m3 = g(d/c)m3

#15

Front (Question)

difference btw concentration & strength

Back (Answer)

-more con. more H+ ions, more products -stronger, faster rate of reaction

#16

Front (Question)

define alkaline

Back (Answer)

water soluble base

#17

Front (Question)

define acid & base

Back (Answer)

acid - proton donners; source of H+ ions base - proton acceptors; source of OH- ions

#18

Front (Question)

why are H+ ions called protons

Back (Answer)

-e is given away -only neutron & proton in nucleus -proton had + charge

#19

Front (Question)

relationship btw pH & ions

Back (Answer)

-higher the concentration of H+ ions, lower the pH -higher the concentration of OH- ions, higher the pH

#20

Front (Question)

pH of acid, neutral, alkaline

Back (Answer)

acid - <7 neutral - 7 base - >7

#21

Front (Question)

pH of metal oxides, hydroxides & carbonates

Back (Answer)

basic

#22

Front (Question)

pH of non- metal oxides, hydroxides & carbonates

Back (Answer)

acidic

#23

Front (Question)

define solute, solvent, solution

Back (Answer)

solute - substance which dissolved in solvent solvent - substance which solute dissolves in solution - mixture of solute & solvent

#24

Front (Question)

define metalloids

Back (Answer)

-non- metals with metallic properties eg. boron, silicon
