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.
Do strong acids always have a lower pH than weak acids?
Yes, strong acids dissociate more completely in water, leading to a higher concentration of H+ ions and a lower pH compared to weak acids which don't fully dissociate.
How are acids and bases different and how do their pH values differ?
Acids release hydrogen ions when dissolved in water, lower the pH, and have a pH value less than 7. Bases accept hydrogen ions when dissolved in water, increase the pH, and have a pH value higher than 7. Acids and bases neutralize each other to form water and a salt in a chemical reaction called neutralization.
Do alkalis have a pH less than 7?
No, alkalis have a pH greater than 7, typically ranging from 7 to 14 on the pH scale. They are known to be basic substances that can neutralize acids.
What is the relationship between pH and acids and bases?
pH is a measure of the concentration of hydrogen ions in a solution, with lower pH values indicating higher acidity and higher pH values indicating higher alkalinity. Acids have pH values below 7, while bases have pH values above 7. Acids release hydrogen ions in water, lowering pH, while bases release hydroxide ions, raising pH.
What has a pH higher than 7?
acids

Do both acids and bases have a pH higher than 7?
yes because acids are corrosive

How can you tell acids from bases?
Acids have a lower PH and bases have a higher PH.

Is acid rain has a higher than normal pH?
No, acid rain has a lower than normal pH due to the presence of sulfur dioxide and nitrogen oxides in the atmosphere, which combine with water vapor to form sulfuric and nitric acids. This lowers the pH of the rainwater, making it acidic.

What is true about bases on the pH scale?
Bases have values higher than 7 Substances with a pH of 7 are neutral Acids have a pH below 7
What are the basic properties of basics in chemistry?
pH value is higher than 7 and reacts with acids
Does a base have a pH of greater or less than 7?
no acids are higher than seven and bases are lower than seven
