What is the effect of dilution on the pH of strong acid?
Diluting a strong acid will generally have little effect on its pH. This is because strong acids completely dissociate in water to give H+ ions, so adding more water will not change the concentration of H+ ions significantly. Therefore, the pH of a strong acid solution remains relatively constant upon dilution.
How does the pH change when the solution of acids is diluted with water?
When an acid solution is diluted with water, the pH will increase. This is because dilution reduces the concentration of the acid, resulting in a lower concentration of hydrogen ions in the solution, which in turn raises the pH.
Is it true that a ten-fold dilution of a strong acidic solution will decrease the pH by 1?
No, it is false. A ten-fold dilution of an acid will INCREASE the pH by 1 unit. Remember pH is 0-14 where 0 is most acidic. Diluting ten-fold on a logarithmic scale will increase the pH.Conversely, a ten-fold dilution of an alkali/base will increase the pH by 1 unit.
Will the pH change when an alkali is added to an acid?
Yes, the pH will change when an alkali is added to an acid. The addition of an alkali to an acid will result in the neutralization reaction, forming water and salt. This reaction will change the pH towards being more neutral.
How can you differentiate strong acid from a weak acid using an indicator?
You can differentiate between a strong acid and a weak acid using an indicator by examining the pH change. A strong acid will cause a more significant decrease in pH and produce a more intense color change in the indicator compared to a weak acid, which will cause a less dramatic change in pH and produce a less intense color change.

Does dilution make an acid weaker?
Dilution of acid does not change its chemical properties, so the acid itself is not weaker. However, dilution can reduce the concentration of the acid in a solution, making it less corrosive or less likely to cause harm upon contact.

No, it is false. A ten-fold dilution of an acid will INCREASE the pH by 1 unit. Remember pH is 0-14 where 0 is most acidic. Diluting ten-fold on a logarithmic scale will increase the pH.Conversely, a ten-fold dilution of an alkali/base will increase the pH by 1 unit.
What is the maximum pH attained upon infinite dilution of an acid?
Trick question ? If you dilute with water then eventually the pH will approach 7 (approximately, since water seldom has a true pH of 7).
Why does the pH of an acetate buffer increases after dilution with water?
The increase in pH of an acetate buffer after dilution with water is due to the decrease in the concentration of the acetic acid and acetate ions in the solution. This decreases the buffering capacity of the solution, causing the pH to shift towards the pKa of acetic acid (4.76) as the system is no longer able to resist changes in pH as effectively.
What happens when 10cm cubed of pH1 acid is added to 90cm cubed of water?
When 10 cm³ of pH 1 acid is added to 90 cm³ of water, the resulting mixture will have a diluted acid solution. The total volume becomes 100 cm³, and the pH will increase from 1 towards a higher value, depending on the acid's concentration and the dilution factor. This occurs because the addition of water decreases the concentration of hydrogen ions (H⁺) in the solution, leading to a higher pH. The exact pH can be calculated using dilution equations and the dissociation constant of the acid.
Will the pH change when an alkali is added to an acid?
Yes, the pH will change when an alkali is added to an acid. The addition of an alkali to an acid will result in the neutralization reaction, forming water and salt. This reaction will change the pH towards being more neutral.
How does neutralization change the pH value of an acid?
When an acid is neutralized, its pH value is changed to be around 7 and it is no longer an acid.
How can you differentiate strong acid from a weak acid using an indicator?
You can differentiate between a strong acid and a weak acid using an indicator by examining the pH change. A strong acid will cause a more significant decrease in pH and produce a more intense color change in the indicator compared to a weak acid, which will cause a less dramatic change in pH and produce a less intense color change.
On addition of concentrated Hydro chloric acid to water does the pH of the acid change?
The pH of the hydrochloric acid does not change when it is added to water since it is already highly acidic. The concentration of the acid will remain the same, which means the pH will also remain constant.
What factor affect pH of buffer?
The pH of a buffer solution is primarily influenced by the ratio of the concentrations of its conjugate acid-base pair. Any changes in the concentrations of the acid or base components will affect the buffer's pH. Additionally, temperature changes can also impact the pH of a buffer solution.
