Does the addition of water (baking soda plus water) alter the pH of weak acidsbasesHow does it changethe pH of srong acidsbases Why or why not?
The addition of water to weak acids or bases generally dilutes the solution, which can lead to a slight increase in pH for weak acids and a decrease in pH for weak bases due to the equilibrium shifting. In contrast, adding water to strong acids or bases typically results in a more significant change in pH, as strong acids and bases dissociate completely in solution. Therefore, dilution with water for strong acids will lower the pH (less acidic) and for strong bases will raise the pH (less basic) but will still remain strongly acidic or basic depending on their original concentration. Overall, the extent of pH change depends on the strength and concentration of the acid or base involved.
Which solutions showed the greatest change in pH why?
The solutions that showed the greatest change in pH are typically those with strong acids or strong bases, as they fully dissociate in water, leading to a significant increase or decrease in hydrogen ion concentration. For example, adding hydrochloric acid (HCl) to water will dramatically lower the pH, while adding sodium hydroxide (NaOH) will raise it significantly. Additionally, buffers may show less pH change because they resist alterations in pH due to the presence of weak acids or bases that can neutralize added acids or bases.
What are weak acids or weak bases that can react with strong acids or bases to keep the pH?
Solutions containing these mixtures are called buffers.
Does a weak acid resist a change in the pH?
No, weak acids do not resist changes in pH as strongly as strong acids do. This is because weak acids only partially dissociate in solution, so they contribute less to maintaining a stable pH compared to strong acids.
What are the characteristics of a strong base or strong acid?
A strong base or strong acid completely dissociates in water, producing a high concentration of ions. Strong acids have a low pH and can donate protons easily, while strong bases have a high pH and can accept protons readily. Strong acids and bases are highly reactive and can cause severe burns or tissue damage.
What is the lowest pH to the highest pH?
Lowest pH, strong acids, then weak acids, then salts of strong acids and strong bases, then salts of weak acids and strong bases, then weak bases, then strong bases. All very confusing!
What are the pH values of acids Bases?
Acids have pH values below 7.0. Bases have values above 7.0.

What is a Chemical compounds that converts strong acids or bases into weak acids or bases?
A chemical compound that converts strong acids or bases into weak acids or bases is called a buffer. Buffers help to stabilize the pH of a solution by absorbing excess hydrogen or hydroxide ions, thereby minimizing changes in pH when strong acids or bases are added.
Is it true buffers are weak acids or bases that can react with strong acids or bases to prevent sudden changes in pH?

Do strong acids have a higher or lower pH than weak acids?
Strong acids have a lower pH than weak acids. This is because strong acids completely dissociate in water to release all their hydrogen ions, resulting in a high concentration of H+ ions and a lower pH. Weak acids only partially dissociate, leading to a lower concentration of H+ ions and a higher pH.
What are some examples of buffers?
Buffers are weak acids or bases that can react with strong acids or bases to prevent sharp, sudden changes in pH....
How can you tell acids from bases?
Acids have a lower PH and bases have a higher PH.

What type of substances can make th pH of water change?
Both acids and bases.
