What is the ph of neutral substances?
7
What two substances cause corrosion?
oxygen and low pH (acidic) substances.
What has the pH of 5.5?
Many substances have a pH of 5.5. For example, everyday rainwater has a pH from 5 to 6.5 usually.
What are pH strips?
pH strip are strips that tell you what substances are acids alkali or neutral
What is the pH level of 1 molar of sulfuric acid?
pH is almost zero.
Is there something with a pH level lower than 2?
Yes, the pH scale traditionally ranges from 1-14. However it is possible to acheive solutions/substances that have a pH below zero. Hydrochloric acid has a pH of around 1.
What is the importance of knowing pH levels of substances to the wider community?
substances of ph
How do certain substances affect the pH level of tap water?
Acidic substances will lower pH and more alkaline or basic substances will put it above the neutral value of pH = 7
Substances acts to stabalize the pH of the solution?
Substances that act to stabilize the pH of a solution are called buffers.
Why do some substances with high pH burn your skin while substances of similar pH do not burn your skin?
The pH is not the only risk factor of a substance.
What has a pH of about 3?
Substances with a pH level of below 7 are said to be acidic and substances above the pH level of 7 are alkaline. An example of a substance with the pH of about 3 is orange juice.
Why are acidic substances lower in pH value than basic substances?
because the substance is high on pH value because the substance is high on pH value
How does pH enter freshwater?
Water will always have a pH. pH is a measure of how acidic or basic a solution is. Intruduction of basic substances such as carbonates will raise pH. Introduction of acidic substances such as carbonic or sulfuric acid will lower pH.
What is the ph of neutral substances?
7
Can an aqueous solution have a pH of zero?
No. pH is a log scale. You can't have a pH of zero. ---- Above answer left in to correct a misconception. Yes, you certainly can have a pH of zero. A 1 molar solution of a strong acid has a pH of zero, and stock HCl (roughly 12 molar) has a pH of about -1.1 or so. pH is the negative log of the hydrogen/hydronium ion concentration, which for a strong acid is approximately the same as the acid concentration. The log of 1 is zero, therefore the pH of a 1 molar solution of a strong acid is zero. The log of 10 is 1, therefore the pH of a 10 molar solution of a strong acid is -1.
What two substances cause corrosion?
oxygen and low pH (acidic) substances.
What are PH Substances higher than 7?
