Q

Acids- Electrical Conductivity

A

Acids are ionic compounds, their reaction with water allows acids to dissociate
into ions

Ions make acids good electrical conductors because of the charges

Q

Determining Acidity and Basicity

A

The acidity and basicity of a chemical can be determined through various
methods

pH Scales determine through a scale

Acid-Base Indicators determine through colour change

Q

pH Scale

A

Quantitatively measures the acidity or basicity of a chemical based on a scale that ranges
from 1-14

Less than 7 is acidic

7 is neutral

More than 7 is basic

17
Q

Logarithmic scale

A

pH = -log10 [H+] ***

18
Q

Acid-Base Indicators

A

Substances used to qualitatively measure the pH of different substances

Depending on the indicator used, the change in colour will be different for
whether the chemical is acidic or basic

19
Q

Colors?

A

Red (less than 7ph) acidic- Base (more than 7ph)

20
Q

Cleaners

A

(mostly bases)
can be quite detrimental to
the user’s health

21
Q

The mixing of bleach (NaClO) (a compound containing chlorine), and ammonia
(NH3)

A

can have dire consequences

22
Q

Symbols
fire
skull
boom
hand

A

flammable
