List 3 properties of a Base?
-
Sour, slippery, changes colors.
-
Slippery, shiny, bitter.
-
Biter, ablitity to change colors in an indicator, and slippery.
-
None of the above
Correct Answer
A. Biter, ablitity to change colors in an indicator, and slippery.Explanation
The correct answer is "biter, ability to change colors in an indicator, and slippery." This answer lists three properties of a base, which are being bitter, having the ability to change colors in an indicator, and being slippery. These properties are commonly associated with bases and can be used to identify them in various chemical reactions or experiments.Rate this question:

What is the product of neutralization?
-
Sugar
-
Salt
-
Water
-
Salt water
Correct Answer
A. Salt waterExplanation
Neutralization is a chemical reaction between an acid and a base, resulting in the formation of a salt and water. The product of neutralization is therefore salt water, as the acid and base combine to form a salt compound and water molecules.Rate this question:

An acid is a proton donor.
-
True
-
False
Correct Answer
A. TrueExplanation
An acid is a substance that can donate a proton (H+) to another substance. This definition is based on the Bronsted-Lowry theory of acids and bases. According to this theory, acids are proton donors, while bases are proton acceptors. Therefore, the statement "An acid is a proton donor" is true.Rate this question:

Strong bases dissociate only slightly in water.
-
True
-
False
Correct Answer
A. FalseExplanation
Strong bases actually dissociate completely in water, meaning that they break apart into ions. This is in contrast to weak bases, which only dissociate partially. Therefore, the statement that strong bases dissociate only slightly in water is incorrect.Rate this question:
-
- 6.
Weak bases dissociate almost completely when dissolved.
-
True
-
False
Correct Answer
A. FalseExplanation
Weak bases do not dissociate completely when dissolved in water. Unlike strong bases, weak bases only partially ionize in water, resulting in a lower concentration of hydroxide ions. Therefore, the statement is false.Rate this question:

Define an acid?
-
Produces H3O+ when dissolved in water.
-
Any substance with a ph of 8
-
Is bitter, has the ability to change color in an indicator, and is reative with meatal.
-
None of the above
Correct Answer
A. Produces H3O+ when dissolved in water.Explanation
An acid is defined as a substance that produces H3O+ ions when dissolved in water. This is because acids are proton donors, meaning they release hydrogen ions (H+) in aqueous solutions. These hydrogen ions then combine with water molecules to form hydronium ions (H3O+). Therefore, the correct definition of an acid is that it produces H3O+ when dissolved in water.Rate this question:

What is the scale used by chemists to measure the concentration of Hydronium Ions in a solution?
-
An indicator
-
PH
-
Hp
-
None of the above
Correct Answer
A. pHExplanation
Chemists use the pH scale to measure the concentration of Hydronium Ions in a solution. The pH scale measures the acidity or alkalinity of a solution, with a pH of 7 being neutral, values below 7 indicating acidity, and values above 7 indicating alkalinity. Therefore, pH is the correct answer for this question.Rate this question:

Strong Acids ionize almost completely in water.
-
True
-
False
Correct Answer
A. TrueExplanation
Strong acids are substances that ionize completely in water, meaning that they break apart into their constituent ions. This results in a high concentration of hydrogen ions (H+) in the solution. Therefore, the statement that strong acids ionize almost completely in water is true.Rate this question:

Which of the following is an acid?
-
Sulfuric
-
Hydrochloric
-
Phosphoric
-
All of the above
Correct Answer
A. All of the aboveExplanation
All of the options listed (Sulfuric, Hydrochloric, and Phosphoric) are examples of acids. Acids are substances that release hydrogen ions (H+) when dissolved in water. Sulfuric acid (H2SO4), hydrochloric acid (HCl), and phosphoric acid (H3PO4) are all strong acids that dissociate completely in water, producing H+ ions. Therefore, all three options are correct answers as they are all acids.Rate this question:
