In a test that uses phenolphthalein, an indicator that it is basic is a color change to ______

In a test that uses phenolphthalein, how can the substance be classified if it remains colorless?

ACID, NEUTRAL, or BASE: Distilled water

ACID, NEUTRAL, or BASE: Cow’s milk

ACID, NEUTRAL, or BASE: Ammonia solution

TRUE OR FALSE: The strength of an acid or base is not related to its concentration.

What ions are formed when strong acids readily react with water?

What ions form when strong bases readily reacts with water?

Weak acids or bases are only _________ ionized in an acqueous solution.

He defined acids as substances that contain a hydrogen atom and dissolve in water to form a hydrogen ion.

This definition was said to be limited and inaccurate because hydrogen ions do not exist in water; rather, hydronium ions are present.

The Bronsted-Lowry definition states that substances that donate a proton are called ______ while substances that accepts a proton are called ______.

These can be charges of acid, according to the Bronsted-Lowry definition.

Bases, according to the Bronsted-Lowry definition, can have either one of these charges.

This is what you call substances that can act as either an acid or a base.

These are acids that can give up only one proton.

These are acids that can give up only two protons.

Classify the given acid: HNO3

Classify the given acid: H3PO4

This is a substance formed when an acid donates a proton to another molecule.

This is a substance formed when a base accepts a proton from another molecule.

Give the conjugate base of the following acid: NH3

Give the acid pair of this conjugate base: H2O

TRUE OR FALSE: The strength of the acid/base is inversely proportional with the strength and reactivity of its conjugate acid/base.

TRUE OR FALSE: Bronsted-Lowry bases are also Lewis bases.

pH means:

TRUE OR FALSE: The lower the pH value, the higher the corresponding concentration of H+

This is a scale which measures how acidic or basic a substance is.

Type in the formula for finding the pH if the concentration is present.

Type in the formula for finding the pOH if the concentration is present:

Type in the formula for finding the [H3O+] if the pH is present.

Type in the formula for finding the [OH-] if the pOH is present.

What should be the number of decimal places for a pH value if the concentration is 3.5x10-3?

This is a substance that resists changes in pH.

A buffer is made up of a __________ or a base and its _________.

Which among the following are functions of a buffer?

Buffer in both plasma and cells.

Most important protein buffer.

Buffers renal tubules and intracellular fluids, providing a temporary solution.

The most important extracellular buffer.

This physiological buffer regulates the blood levels of carbonic acid.

This physiological buffer is the most effective pH regulator.

TRUE OR FALSE: If kidney fails, pH balance will fail.

The acid-base balance in body fluids is one of the most vital aspects of what?

This acid-base balance disturbance is the build up of too much acid in the body.

This acid-base balance disturbance is the build up of too much base in the body.

This disturbance is caused by an excessive loss of H3O+ from the blood.

This disturbance is caused by a buildup of CO2 in the blood due to poor lung function or depressed breathing.

This disturbance is caused by a loss of acid from the blood.

This disturbance is caused by a low level of CO2 in the blood that results from rapid or deep breathing.

It is an equilibrium constant for the ionization of an acid in aqueous solution to H3O+ and its conjugate base, also called as an acid dissociation constant.

The formula of pKa.

The weaker the acid, the smaller its Ka, the larger its pKa, and the higher its pH. The strength of the acid and its pH is:

It is the amount of hydronium or hydroxide ions that a buffer can absorb without a significant change in its pH.

TRUE OR FALSE: The greater the concentration of the weak acid and its conjugate base, the greater the buffer capacity.

The buffer can resist a pH change with added acid or base if its buffer capacity is more ______.

This equation calculates the pH of a buffer when the concentrations of the weak acid and its conjugate base are not equal.
