Solutions
A mixture of substances that is uniform(or the same) throughout and whose particles cannot be separated easily is called what?
What is solution
An acid is a substance that produces ___________ ions(H+) in a solution.
What is hydrogen
A base is a substance that produces hydroxide ions in a solution. What is the symbol for hydroxide ions? Hint: Remember the charge (+) or (-).
What is OH-
The Ph scale measures the strength of acids and bases. What is the range of numbers used to measure Ph?
What is 0-14
Ph strips, or litmus paper, change color in the presence of an acid or base. What is the correct term for any tool that changes color from acids/bases?
What is indicator
What is the difference between the solute and the solvent in a solution?
The solute is in a smaller amount and gets dissolved; the solvent is in a larger amount and does the dissolving.
Acids have this kind of taste...
What is sour
Unlike acids, most bases are in this form at room temperature. Hint: Solid, liquid, gas, or plasma.
What is crystalline solid
Give the Ph for pure water, a neutral solution.
What is 7
A chemical reaction that occurs between an acid and base in a water solution to form water and salt is called what?
What is neutralization
The ability(or maximum amount) of a solute that can be dissolved in a given amount of solvent at a specific temperature is called what?
What is solubility
Acids(and bases) are corrosive. What does corrosive mean?
What is having the quality of eating away at other substances
What kind of taste is a property of bases?
What is bitter
A strong acid would likely have a Ph of what number?
What is 0, 1, 2, or 3
To speed up the process of dissolving, a person can break down a solid into smaller pieces by crushing it. What is this speeding up process called?
What is increasing surface area
What is the difference between a saturated and unsaturated solution? Hint: Think about percent dissolved in each.
What is saturated contains all solute it can hold at a given temperature(100% capacity); unsaturated is able to dissolve more solute at a given temperature(less than 100%)
What color do strong acids change Ph strips(litmus paper) to?
What is red
What color do strong bases turn Ph strips(litmus paper)?
What is blue
Give a number on the Ph scale for a weak base.
What is any number from 7.1-10.9
Mixing up a solution with a scientific tool is a way of speeding up the dissolving process called what?
What is stirring
When a solution is unstable because it contains more solute than a saturated solution, it is called what?
What is supersaturated.
Acids are electrolytes. Explain what electrolytes are/do.
What is conduct electricity in a solution
When mixed in a solution, bases tend to have this texture when felt. Hint: slime is made this way.
What is slippery
Give an example of a strong acid and a strong base.
What is many answers
acids: battery acid, vinegar, lemon juice, stomach acid, hydroflouric acid, hydrochloric acid, etc.
bases: sodium hydroxide, drain cleaner, oven cleaner, bleach, ammonia, etc.
In order to energize and speed up thee particles in a solution, a person would have to do this in order to speed up the dissolving process.
What is increase the temperature
