Which of the following Ka values represent the weakest acid?

The Ka value closest to 1 x 10^-7 represents the weakest acid, as this value corresponds to a neutral solution and indicates a weaker dissociation of the acid.


What is hydrochloric acid 20 Be?

Hydrochloric acid 20 Be refers to a solution of hydrochloric acid where the concentration is such that it corresponds to 20° Baumé (Be) scale. This scale measures the density of a solution as compared to the density of water. A 20 Be hydrochloric acid solution is typically around 18-20% concentration of hydrochloric acid by weight.


Is a solution with a pH of 10.1 a weak acid?

NO... STRONG ACIDS HAVE A pH VALUE BETWEEN 1 AND 4 ....pH VALUES OF 5 AND 6 ARE WEAK ACIDS AND 7 IS NEUTRAL.


What is the concentration of 5 Baume HCl?

The Baumé scale does not directly measure the concentration of a solution. For example, to determine the concentration of nitric acid from a hydrometer reading, you would need to determine the specific gravity and then utilize a table of known specific gravity values for nitric acid at known concentrations. Using the formula to convert ºBaumé to specific gravity: specific gravity = 145/(145-ºBaumé) you get a specific gravity of 1.0357 for a 5ºBaumé reading on your hydrometer. Then you can go to a table of values, such as the one in the CRC Handbook of Chemistry & Physics (mine is 60th Ed., page D-240) for a table that has various concentration values for specific gravity values. In this case, the closest value of specific gravity to 1.0357 is 1.0352, which corresponds to a 7.50 wt% or a 2.129M HCl solution. Hope this helps!


Is a solution of pH 3 an acid or base?

A solution with a pH of 3 is considered acidic. pH values below 7 indicate acidity, while values above 7 indicate alkalinity. A pH of 7 is considered neutral.

What K value represents the weakest acid?

The K value, or acid dissociation constant (Ka), indicates the strength of an acid in solution. A smaller Ka value corresponds to a weaker acid, as it signifies a lower degree of dissociation in water. Therefore, the weakest acid would have the smallest Ka value, approaching zero, indicating that it does not ionize significantly in solution.


Which ion determines the strength of an acid?

The hydronium ion (H3O+) concentration in a solution determines the strength of an acid. A higher concentration of hydronium ions corresponds to a stronger acid, while a lower concentration indicates a weaker acid.


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.


What happens when pH paper is dipped into acid?

When pH paper is dipped into an acid, it changes color depending on the acidity of the solution. The paper turns a certain color (usually red) to indicate that the solution is acidic. The intensity of the color change corresponds to the pH level of the acid.


What is a typical pH of a weak acid?

A typical pH of a weak acid ranges from about 3 to 6. This range indicates that the acid partially dissociates in solution, resulting in a higher pH compared to strong acids, which usually have pH values below 3. The exact pH can vary depending on the concentration of the acid and its dissociation constant (Ka).


Which amino acid corresponds to these guanine adenine uracil bases?

Adenine corresponds to the amino acid glutamine. Guanine corresponds to the amino acid arginine. Uracil does not correspond to any amino acid directly as it is not involved in protein synthesis in humans.


Is a solution with a pH 6 an acid or a base?

A solution with a pH of 6 is considered acidic. pH values below 7 indicate acidity, while pH values above 7 indicate alkalinity.
