A Bronsted-Lowry acid is a substance that donates a proton (H) in a chemical reaction, while a Bronsted-Lowry base is a substance that accepts a proton. To determine if a substance is a Bronsted-Lowry acid or base, you can look at its behavior in a reaction - if it donates a proton, it is an acid, and if it accepts a proton, it is a base.

How can one determine the acid dissociation constant (Ka) of a substance without using the pH value?
One can determine the acid dissociation constant (Ka) of a substance without using the pH value by conducting a titration experiment. In this experiment, a known concentration of the acid is titrated with a strong base of known concentration. By measuring the volume of base required to neutralize the acid, one can calculate the Ka value using the initial concentrations of the acid and base.
How can one determine a buffer solution?
A buffer solution can be determined by mixing a weak acid with its conjugate base, or a weak base with its conjugate acid. This combination helps maintain a stable pH level when small amounts of acid or base are added.
Is acid-base titration an qualitative or quantitative?
Acid-base titration is a quantitative analytical technique used to determine the concentration of an acid or a base in a solution. By measuring the volume of titrant required to reach the equivalence point, one can calculate the concentration of the analyte in the original solution.
What are the method of titration?
The methods of titration include acid-base titration, redox titration, and complexometric titration. Acid-base titration involves the reaction between an acid and a base to determine the concentration of one of the reactants. Redox titration involves oxidation-reduction reactions to determine the concentration of a substance. Complexometric titration involves the formation of a complex between a metal ion and a complexing agent to determine the concentration of the metal ion.
How can one determine the pH of polyprotic acids?
To determine the pH of polyprotic acids, one can use the stepwise dissociation constants of each acidic proton and calculate the concentrations of the acid and its conjugate base at each stage of dissociation. By considering the equilibrium concentrations of the acid and its conjugate base, one can then use the Henderson-Hasselbalch equation to calculate the pH of the solution.

Strength of acids and bases are determined by extending the acid or base?
by extending the acids and bases one can determine that they will reast with each other.
How can one determine the acid dissociation constant (Ka) from the concentration of a solution?
To determine the acid dissociation constant (Ka) from the concentration of a solution, you can measure the concentrations of the acid, its conjugate base, and the equilibrium concentrations of both in the solution. By using these values in the equilibrium expression for the acid dissociation reaction, you can calculate the Ka value.
How can one determine the acid dissociation constant (Ka) from a titration curve?
To determine the acid dissociation constant (Ka) from a titration curve, one can identify the equivalence point on the curve where the amount of acid equals the amount of base added. By analyzing the pH at the equivalence point and using the initial concentration of the acid, the Ka can be calculated using the Henderson-Hasselbalch equation.
How can you tell if the burrette contains the acid or base?
You can determine if a burette contains acid or base by using a pH indicator. Simply add a few drops of the indicator to the solution in the burette and observe the color change. Red or pink indicates an acid, while blue or green indicates a base.
Why is acid-base titration a useful technique in chemistry?
Acid-base titration is useful in chemistry because it allows for the precise determination of the concentration of an acid or base in a solution. By measuring the volume of titrant needed to neutralize the analyte, one can calculate the concentration of the unknown solution. This technique is commonly used in quantitative analysis and in determining the purity of chemicals.
How could you safely determine if a base is stronger than an acid?
Use an electronic pH meter. If an acid registers '3' on a pH meter and an alkali registers '13' on a pH meter, then the alkali is the stronger. Because the acid has 'two' steps to because the strongest acid at pH = 1 , but the alkali has only 'one' step to become the strongest alkali at pH = 14. 1 - 14 are the limits of the pH scale.
What is the laboratory method used to determine the concentration of an acid?
One common method to determine the concentration of an acid is titration. In an acid-base titration, a solution of known concentration (titrant) is added to the acid solution until the reaction is complete, as indicated by a color change with an indicator or a pH meter. The volume of titrant used is then used to calculate the concentration of the acid.
