pH scale: a scale used to measure how acidic or basic a liquid is

Acids: a special kind of chemical that has a lot of hydrogen ions; reads less than 7 on the pH scale (Lemon, orange, tomato juices)

Bases: a special kind of chemical that has a lot of hydroxide ions; reads more than 7 on the pH scale (saltwater, soapy water, bleach)
2
What is the pH scale used for?
to measure how dirty the water is
to determine the temperature of the water
to measure how acidic or basic the water is
3
The pH scale is used for measuring how acidic or basic a water sample is.The pH scale runs from 0-14, with the number 7 being neutral. A number above 7 represents a basic solution and a number below 7 represents an acidic solution. (Image credit: Loggerhead Marinelife Center)
4
All aquatic species are adapted to live at the same temperature.
YESNO
5
No, each aquatic species has their own temperature range needed for survival. Some species are adapted to live in the very cold temperatures of the arctic, while other species are adapted to live in the warm waters of Florida. Each species has their own needs based on the habitat that they live in. (Image credit: Loggerhead Marinelife Center)
6
The term turbidity refers to how cloudy the water is.
YESNO
7
Yes, the term turbidity refers to how cloudy the water is or how many particles are suspended in the water .The secchi disk is a tool used to measure turbidity in bodies of water. (Image credit: Loggerhead Marinelife Center)
8
Which of the following are common water quality parameters tested?
pH
Turbidity
Temperature
Dissolved Oxygen
9
Turbidity, pH, temperature, and dissolved oxygen are all common water quality parameters tested.These are NOT the only ones! There are many additional water parameters that can be tested including tests for nitrates, alkalinity, and phosphorous. (Image credit: Loggerhead Marinelife Center)
10
What does dissolved oxygen refer to?
a measure of how much oxygen is dissolved in the water
the amount of oxygen that is available to aquatic organisms
the amount of oxygen that is available to humans
11
Dissolved oxygen is a measure of how much oxygen is dissolved in the water and therefore how much oxygen is available to aquatic organisms.Similar to how humans breathe oxygen through the air, fish breathe with gills which take in dissolved oxygen from the water.
