What are some properties of acids?

• Does not react with bases

• Odorless

• ability to corrode metals

• Ability to form oxygen

What are acid-base indicators and what are they used for?

• Acid-base indicators are substances used to measure the temperature of a solution.

• Acid-base indicators are substances that change color depending on the pH of a solution. They are used to determine if a solution is acidic, neutral, or basic.

• Acid-base indicators are substances used to increase the pH of a solution.

• Acid-base indicators are substances used to clean acidic or basic surfaces.

How is the strength of an acid measured?

• The strength of an acid is measured by its pH value.

• The strength of an acid is measured by the amount of electrons it releases

• The strength of an acid is measured by the temperature at which it is found

• The strength of an acid is measured by the amount of water it contains

What is the concept of pH?

• The concept of pH refers to the measurement of temperature of a solution

• The concept of pH refers to the measurement of salinity of a solution

• The concept of pH refers to the measurement of density of a solution

• The concept of pH refers to the measurement of acidity or alkalinity of a solution, on a scale from 0 to 14.

What is the pH of a neutral solution?

• 5

• 7

• 3

• 10

What happens to the pH when an acid is added to a solution?

• The pH decreases

• The pH remains constant

• The pH increases

• The pH does not change

What is the pH range for a basic substance?

• Between 0 and 7

• Less than 7

• Equal to 7

• Greater than 7

What is neutralization in the context of acid-base reactions?

• Neutralization is the process in which an acid and a base react to form ammonia and sodium chloride.

• Neutralization is the process in which an acid and a base react to form hydrogen and nitrogen.

• Neutralization in the context of acid-base reactions is the process in which an acid and a base react to form water and a salt.

• Neutralization is the process in which an acid and a base react to form oxygen and carbon dioxide.

What is the relationship between pH and the concentration of hydrogen ions in a solution?

• As the concentration of hydrogen ions increases, the pH decreases.

• The pH decreases as the concentration of hydrogen ions remains constant.

• The pH and the concentration of hydrogen ions are not related.

• As the concentration of hydrogen ions increases, the pH increases.

What are some common properties of bases?

• React with acids

• Bitter taste, slippery feel

• Odorless

• Ability to form oxygen
