How is the strength of a weak acid related to the strength of its conjugate base?
Strong acids and bases dissociate completely in water. Strong acids produce a pH of less than 3 and form weak conjugate bases. Strong bases produce a pH greater than 10 and form a weak conjugate acid.
What happens in a buffer when the level of H ions in solution increases?
When the level of H+ ions in solution increases, a buffer will help to minimize the change in pH by reacting with the excess H+ ions. In an acidic buffer, the conjugate base will react with the additional H+ ions to form the weak acid component. In a basic buffer, the weak acid component will react with the extra H+ ions to form the conjugate base and restore equilibrium.
What kind of ions do bases form?
Bases typically form hydroxide ions (OH-) when they dissolve in water. These hydroxide ions are responsible for the basic properties of the solution.
What ions do Nitric acid form in water?
HNO3 dissociates to give H+ and NO3- ions.
A substance in a solution that releases and captures hydrogen ions keeping the PH the same?
A buffer is a substance in a solution that can absorb excess H+ ions or donate H+ ions to help maintain a stable pH. Buffers are essential for minimizing changes in pH in biological systems and are made up of a weak acid and its conjugate base or a weak base and its conjugate acid.
What do acids and water separate into?
Acids in water will (partially)split into ions: protons (H+) and anions (conjugate base ions.

What happens in a buffer when the levels of H ions in solution increase?
When the levels of H+ ions in solution increase, a buffer will work to maintain a relatively constant pH by either accepting or donating H+ ions to resist changes in acidity. This is achieved through the buffer's components, which are typically a weak acid and its conjugate base or a weak base and its conjugate acid.

Explain how the relationship between the strengths of an acid and its conjugate base and of a base and its conjugated acid?
If acid is strong then its conjugate base must be weak, if conjugate base is strong it again accept the H+ ions so acid can neither be strong, similarly if base is strong its conjugate acid must be weak.
What happens in a buffer when the level of H ions in solution increase?
When the level of H+ ions in solution increases, a buffer system will resist large changes in pH by either accepting excess H+ ions through their conjugate base component or releasing H+ ions through their conjugate acid component. This helps to maintain the pH of the solution relatively stable.
An atom differs in electric charge from what?
An atom differs in electric charge from ions because atoms are electrically neutral, containing equal numbers of protons and electrons. Ions are charged particles resulting from atoms that have gained or lost electrons, creating an imbalance in the number of protons and electrons.
Which is produced when a base reacts with water?
When a base reacts with water, it produces hydroxide ions (OH-) and the conjugate acid of the base. This reaction is known as hydrolysis.
What does acid turn into after it sits in water?
When an acid is dissolved in water, it forms ions such as hydronium ions (H3O+) and the corresponding conjugate base. The extent to which an acid dissociates in water depends on its strength.
