Front (Question)

Define Acid

Back (Answer)

substances that produce H⁺ ions

Front (Question)

Name 3 examples of acids

Back (Answer)

H₂SO₄ , HNO₃ , HCl , H₃PO₄

Front (Question)

Fill in the blanks: In solutions, acids produce a pH ___ at rtp.

Back (Answer)

< 7

Front (Question)

Are Non-metal oxides acids or bases?

Back (Answer)

acids

Front (Question)

What happens when an acid dissociates?

Back (Answer)

it produces H⁺ ions which is what makes a solution acidic.

Front (Question)

What happens when a non-metal oxide reacts with water?

Back (Answer)

forms an acid

Front (Question)

Where do acids produce H⁺ ions?

Back (Answer)

ONLY IN WATER

Front (Question)

Why is HCl either an acid or neutral depending on the type of bonding it has?

Back (Answer)

If HCl has ionic bonding, it can dissolve in water, therefore dissociating to release H⁺ ions which is what makes a solution acidic. If HCl has covalent bonding, it is insoluble in water so no H⁺ ions can be released because they can dissociate.

Front (Question)

Define bases

Back (Answer)

substances that react with acids to form water

#10

Front (Question)

What ion do most bases produce in water?

Back (Answer)

OH⁻

#11

Front (Question)

Define neutralisation reaction

Back (Answer)

when an acid and a base react to produce water

#12

Front (Question)

acid + base →

Back (Answer)

salt + water

#13

Front (Question)

NH₃ + H₂O →

Back (Answer)

NH₄OH (ammonia)

#14

Front (Question)

NH₄OH → (dissociated)

Back (Answer)

NH₄ + OH⁻

#15

Front (Question)

Define alkali

Back (Answer)

base which dissolves in water, specifically group 1 metal hydroxides / carbonates

#16

Front (Question)

What does the pH >7 (if the base dissolves) measure?

Back (Answer)

the concentration of acids / bases

#17

Front (Question)

Define Ionic equation

Back (Answer)

an equation that only shows the change in chemicals

#18

Front (Question)

What has to happen in order for a neutralisation reaction to react a pH of 7?

Back (Answer)

the acid and the base have to react in equal molar quantities (H⁺ + OH⁻)

#19

Front (Question)

What is the logarithmic scale for pH?

Back (Answer)

The scale where e.g. pH 3 is ten times more acidic than pH 4 and pH 3 is 100 times more acidic than pH 5. Likewise, pH 11 is 10 times more basic than pH 10.

#20

Front (Question)

THE PH DOES NOT DIRECTLY RELATE TO THE DANGER OF AN ACID/BASE

Back (Answer)

ok…

#21

Front (Question)

What does concentration measure?

Back (Answer)

the moles of a substance dissolved in a specific volume of solvent (water)

#22

Front (Question)

What is the unit of concentration?

Back (Answer)

mol / dm³ ⤵ ↓ volume moles of of solvent solute

#23

Front (Question)

1 dm³ =

Back (Answer)

1,000 cm³

#24

Front (Question)

Fill in the blanks: The concentration of an acid is a measure of the _____________________ dissolved in any solvent.

Back (Answer)

number of moles
