What is the scientific difference between seawater and freshwater?
Seawater has a higher concentration of salts and minerals compared to freshwater. Seawater also has a higher density and freezes at lower temperatures than freshwater. Additionally, seawater has a higher pH and different composition of dissolved gases compared to freshwater.
Why is the sea water and freshwater pH different?
The pH of seawater is typically higher than freshwater due to the presence of minerals and salts, which can buffer against changes in acidity. Freshwater bodies are more vulnerable to changes in pH because they lack these buffering compounds. Human activities such as pollution and acid rain can also contribute to fluctuations in freshwater pH.
What is freshwater on the pH scale?
Freshwater typically has a pH ranging between 6.5 and 8.5, which is considered slightly acidic to slightly alkaline. This pH range allows freshwater ecosystems to support a variety of plant and animal life. Any significant deviations from this range can have harmful effects on aquatic organisms.
How many times acidic is urine with the pH level of 6 than seawater with a pH of 8?
Urine with a pH of 6 is 100 times more acidic than seawater with a pH of 8. This is because the pH scale is logarithmic, with each unit change representing a tenfold difference in acidity or alkalinity.
Using the pH scale sea water and bleach solutions are?
seawater is 8 and i believe bleach is somewhere near 12
How is each step on the pH scale different?
The pH scale is logarithmic; the difference between two units is x10.
What is the pH scale for fizzy drinks?
Approx. 3-4; the pH is different for each drink.
How can you use the litmus paper to develop a pH scale?
After studying the color of litmus at different pH.
What can use to make pH scale indicator?
Indicators are substances sensitive to different ranges of pH.
What is the pH of seawater?
The pH of seawater typically ranges from 7.5 to 8.4, making it slightly alkaline. This level can vary based on location, depth, and other factors, but seawater is generally considered to be fairly stable in terms of pH.
What scale is used to determine pH?
the pH scale
What scale describes the acidity of a solution as a number?
the pH
