Acid Concentration in Household Items - Coggle Diagram
Acid Concentration in Household Items
Ways to determine quantity of an acid
Titration
Indicator
Methyl Red
Methyl orange
phenolphthalein
bromethyl blue
What if the mixture is not colourless?
Difficult to determine colour changes
End point is impossible to assess
Must know type of acid present
What if more-than-one type of acid is present?
pH changes will be unpredictable
Indicator will not be representative of the reaction's completion
Titration practical impossible when more-than-one acid in the solution form
Apparatus required
Burette
Volumetric Pipette
Volumetric Flask
Precise scales
Universal Indicator
Simply determines pH of substance
pH Meter
Impractical and expensive to attain
Only determines pH of item
Household Items
Food/ Beverages
Whether something is safe to
ingest based on its quantity of acid
Whether it is healthy in short and long terms
Cleaning products
Safety of use on different surfaces
Safety for human touch
Potential to cause damage to precious/
expensive items if used
Medicine
Antacid
Designed to reduce problematic
levels of acidity in stomach
Units for 'acid content'
Moles per Litre
Chemical standard convention
Specific acid concentration can be compared
to other chemical compounds' concentrations
w/V %
Likely most useful for everyday use
Most often unit used for acid concentration
in foods/ drinks
g/L
