How does the addition of an base affect a neutral solution?
When a base is added to a neutral solution, the pH of the solution will increase. This is because the base combines with the hydrogen ions in the solution, reducing their concentration. As a result, the solution becomes more alkaline and the pH value rises above 7.
How will addition of water affect the acidity of a highly acidic solution having pH 2?
Adding water to a highly acidic solution with a pH of 2 will dilute the solution, increasing the pH and making it less acidic. This is because water will act as a neutral substance, reducing the concentration of H+ ions in the solution and therefore raising the pH level towards neutrality.
How would addition of HCI affect the pH of a solution?
The addition of HCl to a solution would decrease the pH, making it more acidic. This is because HCl is a strong acid that dissociates in water to release hydrogen ions, which increases the concentration of H+ ions in the solution and lowers the pH.
Why do the two solutions NaCl and CH3COOH have initially different pH values in a buffer solution experiment?
NaCl dissociates to form Na+ and Cl- ions, which do not affect pH since they are neutral species. On the other hand, CH3COOH is a weak acid that partially dissociates in water to form H+ ions, leading to a decrease in pH. This difference in the behavior of the two solutions causes them to have initially different pH values in a buffer solution experiment.
Which factors affect pH?
The factors that affect pH include the concentration of hydrogen ions (H+), the presence of acidic or basic substances, temperature, and pressure. In addition, the pH of a solution can be affected by chemical reactions that either release or absorb hydrogen ions.
How will the addition of water affect the acidity of a highly acidic solution having pH?
The addition of water can affect the acidity of a highly acidic solution in one major way. This addition will bring the pH up closer to 7.

What is the solution growth?
Solution growth refers to the increase in the amount of a solution due to the addition of solute or solvent. This can occur through processes like dissolving, mixing, or dilution. Factors such as temperature, pressure, and concentration can affect the rate and extent of solution growth.
What effect does NA plus have on pH?
The addition of sodium hydroxide (NaOH) increases the pH of a solution by releasing hydroxide ions (OH-) which combine with hydrogen ions (H+) to form water. However, the addition of sodium ions (Na+) alone does not directly impact the pH of a solution.
Which factors affect pH?
The factors that affect pH include the concentration of hydrogen ions (H+), the presence of acidic or basic substances, temperature, and pressure. In addition, the pH of a solution can be affected by chemical reactions that either release or absorb hydrogen ions.
How an acid in the water solution affect the pH of the solution?
The pH is under 7.
Does the order of addition of indivitual vectors affect the final resultant vector?
no it does not affect the outcome
Why addition of water to oxalic doesn't affect the molarity?
Adding water to a solution of oxalic acid does not affect its molarity because the total number of moles of oxalic acid in the solution remains the same. Molarity is calculated based on the number of moles of solute divided by the volume of the solution, so as long as the number of moles of oxalic acid stays constant, the molarity remains unchanged.
How does the presence of an acid in a water solution affect of the pH of the solution?
The presence of an acid lowers the pH of the solution in water.
