Acid Basics
What ions do acids produce in water?
Hydrogen ions (H⁺)
What is a base?
A substance with a pH greater than 7
What pH number is neutral?
7
Which produces hydrogen ions: acids or bases?
Acids
What type of reaction occurs when an acid reacts with a base?
Neutralization reaction.
Are acids found above or below 7 on the pH scale?
Below 7
What ions do bases contain in water?
Hydroxide ions (OH⁻)
Pure water at room temperature is a classic example of what type of solution?
Neutral
Which produces hydroxide ions: acids or bases?
Bases
What two products are usually formed during neutralization?
Salt and water
What is the pH range of acids?
Less than 7
How do bases often feel when touched?
Slippery
If a substance has a pH of 3, is it acidic or basic?
Acidic
Which type of substance usually tastes sour (though you should not taste chemicals in labs)?
Acids
What happens to the pH during neutralization?
It moves closer to neutral (7)
If a solution has many hydrogen ions, is it an acid or a base?
Acid
Are bases above or below 7 on the pH scale?
Above 7
If a substance has a pH of 10, is it acidic or basic?
Basic
Which type of substance often feels slippery?
Bases
What type of solution can form when an acid and base react?
A neutral solution
Why are acids considered acidic in water?
Because they produce hydrogen ions (H⁺)
If a solution contains more OH⁻ ions than H⁺ ions, what type of solution is it?
A base
What number separates acids and bases on the pH scale?
7
Which has a higher pH: acids or bases?
Bases
Why is neutralization important?
It reduces acidity or basicity by balancing H⁺ and OH⁻ ions
