How are acids and basis classified as strong or weak?
Acids and bases are classified as strong or weak based on their ability to dissociate in water. A strong acid or base dissociates completely into ions in water, while a weak acid or base only partially dissociates. This is determined by the equilibrium constant for dissociation reactions.
How is a weak acid different from a strong acid?
A weak acid partially dissociates in water, meaning it does not completely break apart into ions. This results in lower concentration of hydrogen ions in solution compared to a strong acid, which completely dissociates to release more hydrogen ions. Weak acids have a higher pH value compared to strong acids.
What describes an acid which dissociates completely?
An acid that dissociates completely in water is called a strong acid. This means that it fully ionizes into its constituent ions in solution, leading to a high concentration of hydronium ions (H3O+). Strong acids have a high affinity for donating protons to water molecules.
List two strong acids and explain why these acids are considered strong acids?
Hydrochloric acid (HCl) is a strong acid because it completely dissociates in water, producing a high concentration of H+ ions. Sulfuric acid (H2SO4) is a strong acid because it is a strong electrolyte, meaning it fully dissociates into H+ and HSO4- ions in solution.
Is k3po4 a strong or weak base?
Potassium phosphate (K3PO4) is a strong base. It completely dissociates in water to release hydroxide ions, which can accept protons from acids, resulting in a basic solution.
What is the difference between a strong acid and a strong base.?
A strong acids dissociates completely in water to produce hydronium (H3O+) ions A strong base dissociates completely in water to produce hydroxide (OH-) ions

What is always true of weak acids?
Weak acids do not completely dissociate in water, meaning they only partially ionize. This results in a lower concentration of hydronium ions compared to a strong acid at the same concentration. Additionally, weak acids have higher pKa values compared to strong acids.
Why is sulfuric acid a Strong acid?
Because it completely disassociates in solution. The first hydrogen comes off almost 100% of the H2SO4 molecule. The acids that dissociates completely into its compounds in water are known as strong acids.
What does a strong acid do for a chemist?
It dissociates (or ionizes) nearly completely with water.
What is strong about a strong acid?
strong acids dissociate completely into ions in water. i.e. HCl dissociates into H+ and Cl- ions. Weak acids only dissociate partially, therefore they are in an equilibrium state where there is some acid remaining and some ions in solution.
What ionizes completely in solution and is considered to be a strong acid?
HClorHydrochloric acid
What is strong about a strong base?
A strong base completely dissociates to produce hydroxide (OH-) ions in water.
