The chart categorizes substances by acidity or basicity, featuring examples like orange juice (low pH) and bleach (high pH), along with properties such as slippery feel and color changes in indicators.
The given chart appears to represent substances categorized based on their acidity or basicity, with associated properties and indicators. Let's label the chart correctly:
Hydroxide ions
Description: A chemical species containing one oxygen and one hydrogen atom, indicating basicity.
Examples: Commonly found in substances like bleach.
Orange juice
Description: A beverage with a characteristic taste, often perceived as sour.
Acidity: Low pH due to the presence of citric acid.
Slippery
Description: Refers to the feel of a substance, often associated with bases.
Example: Soap, which has a slippery feel when dissolved in water.
Distilled water
Description: Pure water with no ions or impurities.
Acidity: Neutral pH of 7, indicating neither acidic nor basic properties.
Low pH
Description: Indicates acidity.
Example: Orange juice, which has a low pH due to the presence of acids.
Turn indicator red
Description: A color change in an indicator showing an acidic environment.
Example: Indicator turning red in the presence of hydrogen ions.
Hydrogen ions
Description: Positively charged ions indicating acidity.
Examples: Present in acidic substances like tomato juice.
Tomato juice
Description: A beverage with a characteristic taste, often perceived as sour.
Acidity: Contains acids, leading to a low pH.
Sour
Description: A taste associated with acidity.
Example: Tomato juice, which is sour due to acidic content.
Turn indicator blue
Description: A color change in an indicator showing a basic environment.
Example: Indicator turning blue in the presence of hydroxide ions.
Soap
Description: A substance often used for cleaning, exhibiting basic properties.
Feel: Slippery when dissolved in water.
High pH
Description: Indicates basicity.
Example: Bleach, which has a high pH due to its alkaline nature.
In summary, the chart represents substances categorized based on acidity or basicity, with corresponding properties and indicators.
