6.8 pH and Color Change
A solution that has a pH below 7 on the pH scale.
What is an acidic solution?
This is added to decrease the concentration of H3O+ ions in a solution.
What is a base?
This occurred to the indicator when CO2 was dissolved in water.
What is a color change to yellow?
These substances cause universal indicator to change from green toward purple.
What are bases?
The measure of the concentration of H3O+ ions in a solution.
What is pH?
This gas dissolved in water can cause water to become acidic.
What is carbon dioxide?
This is used to measure how acidic or basic a solution is.
What is a pH scale.
This is added to increase the concentration of H3O+ ions in a solution.
What is an acid?
This can be added to reduce the acidity of water from dissolved CO2.
What is a base?
A pH above 7 on the pH scale.
What is a basic solution?
These are known as chemical opposites.
What are acids and bases?
This is lacking in ocean acidification for shell-making organisms.
What is calcium carbonate?
Equal numbers of H3O+ ions and OH- ions in water.
What is a neutral solution?
An acid is added to a basic solution, the solution becomes less basic and moves towards the middle of the pH scale.
What is neutralizing the base?
This could be used as an alternative solution for burning of fossil fuels.
