Answer 6

Apple

Question 7

Tartaric acids

Answer 7

Tamarind, unripe mango

Question 8

Oxalic acids

Answer 8

Tomatoes

Question 9

ascorbic acid

Answer 9

Amla

Question 10

Concentrated and dilute

Answer 10

high amount acid and low acid

Question 11

Strong acids

Answer 11

chloric acid, hydrobromic acid, hydrochloric acid, hydroiodic acid, nitric acid, perchloric acid, and sulfuric acid

Question 12

Weak acids

Answer 12

acetic acid (vinegar), lactic acid, citric acid, and phosphoric acid

Question 13

Dilution of acids

Answer 13

They cause exothermic reactions which break glass and splash around, high amount of heat is produced.
It is 1st put into the water to dilute it, its put into the water slowly. ACID PUT INTO WATER NOT VICA VERDSA

Question 14

Oxyacids
Hydracids

Answer 14

H+O molecules
H+anything but O molecules
Hydrocyanic acid for the above

Question 15

H+ion

Answer 15

Acids produce these things in water, strong acids do more, weak acids do less

Question 16

Dibasic and Monobasic

Answer 16

Produce 2 H+ions per molecule
Produce 1 H+ion per molecule

Question 17

Properties of acids

Answer 17

Sour
Corrosive(burning effect)
Soluble in water
React with active metal(these have high reactivity)
Reacts with carbonates to form salt, water, and CO2
Reacts with bases to form salt and water
Generally stored in glass as it makes metals corrodes

Question 18

Preparation of acids

Answer 18

Dissolving Oxides of non-metals like co2 and everything ending with dioxide in water

Question 19

Cells in our body

Answer 19

Deoxyribonucleic acid DNA

Question 20

Fatty acids

Answer 20

imp components of cell membrane

Question 21

Bases

Answer 21

Hydroxides and oxides of metals
bitter
soapy feel
base+acid=water+salt(neutralisation)

Question 22

Bases soluble in water

Answer 22

Alkalis

Question 23

Copper, magnesium and aluminum hydroxides

Answer 23

They ain’t alkalis as they partially soluble and are weak bases

Question 24

Strong and weak bases

Answer 24

cause burning effect and don’t cause burning effect

Question 25

preprations of bases

Answer 25

Some metals heated in O2 give oxides and then placed in water give hydroxides of metals. some active metals like sodium and potassium react with cold water to form hydroxides

Question 26

Indicators

Answer 26

weak acids or bases that help us test if a substance is more acidic or basic

Question 27

NATURAL INDICATRS

Answer 27

CHINA ROSE TURMERIC LITMUS red cabbage

Question 28

Litmus

Answer 28

MOST COMMONLY USED obtained from lichens used in solution of water paper(blue and red paper)

Question 29

Turmeric

Answer 29

yellow tumreric in water

Question 30

china rose

Answer 30

chine rose petals in water

Question 31

red cabbage

Answer 31

purple colored boiled red cabbage in water

Question 32

Synthetic indicators

Answer 32

artifical indicators

Question 33

phenlphthalein

Answer 33

colorless indicator used in lab

Question 34

methyl

Answer 34

orange-pink colored indicator

Question 35

Neutralisation

Answer 35

acid+base=salt+water heat is evolved

Question 36

Agirculture

Answer 36

Too much acid due to fertilizer base is added()slaked lime soil becomes too basic then organic matter is added to soil, when decomposed realsess acids

Question 37

indegestion

Answer 37

too much acid is bad for the linings in the stomach hence we take antacid like milk of magnesia

Question 38

remedy for sting

Answer 38

all stings contain citrus acid bases= baking soda or calamine solution alkali in wasp sting=vinger neutralize

Question 39

tooth decay

Answer 39

toothpaste contain base alkalis

Question 40

treatment of sewage water

Answer 40

base is treated before dumped in water to protect aqua life

Question 41

regaining shine of tarnished copper articles

Answer 41

copper articles get tarnished due to basic copper carbonates which can be removed by rubbing lemon

Question 42

Answer 43

incomplete neutralization of acid by base, ammonium chloride

Question 44

basic

Answer 44

vice versa, sodium acetate
