What else can I help you with?
How can you tell how strong acids and alkalis are using the pH scale?
Acids have a pH under 7, alkalis have a pH bigger than 7.
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.
The pH of a strong base would be closest to?
The pH scale is from 1-14 Strong acids are 1-4
Are weak acids on the pH scale less than 3?
Weak acids typically have a pH greater than 3. A pH of 3 or lower is generally associated with strong acids, which fully dissociate in solution. Weak acids only partially dissociate, resulting in a higher pH compared to strong acids. Therefore, while weak acids can have a pH below 7, they usually do not reach values as low as 3.
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.
Does strong acids tend to raise pH?
No, strong acids tend to lower the pH of a solution. This is because strong acids donate hydrogen ions (H+) when they dissolve in water, increasing the concentration of H+ ions and lowering the pH.
Which has a lower pH weak acids or strong acids?
strong acid
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 is the ph value of acids?
1-6 1- Strong Acids 6- Weaker Acids
Would you expect strong acids or weak acids to have a lower pH level?
Strong acids would be expected to have a lower pH level compared to weak acids. Strong acids fully dissociate in water to produce a higher concentration of hydrogen ions, resulting in a more acidic solution and a lower 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 colour on the ph scale will show strong acids?
Strong acids will appear at the lower end of the pH scale, typically around 0 to 3. The color associated with strong acids on pH test strips is typically a bright red to indicate the low pH levels.
How can you tell how strong acids and alkalis are using the pH scale?
Acids have a pH under 7, alkalis have a pH bigger than 7.

What are the pH values of acids Bases?
Acids have pH values below 7.0. Bases have values above 7.0.
