Solutions & Solubility
What is a solute
Substance being dissolved
What is dilute?
Small amount of solute in solvent
What is an acid?
Substance that produces H⁺ ions
What is 7?
A neutral pH number
What is an indicator?
Color changing compound used to test acids/bases
What is a solvent?
Substance doing the dissolving
What is concentrated?
Large amount of solute in solvent
What do bases feel like in a solution
They feel Slippery
What is the pH scale?
Scale used to measure acidity/basicity
What is neutralization?
Reaction between acid and base
What is one way to speed up dissolving by crushing a solid
Increasing surface area
What is an unsaturated solution?
Solution that can still dissolve more solute
What do acids taste like?
They taste sour
What happens to strong acids when they are almost completely in water?
ionization
What is a salt?
Compound formed during neutralization
What is solubility?
Maximum amount of solute that dissolves at a certain temp
What is a saturated solution?
Solution containing all the solute it can hold
What is a base?
Substance that produces OH⁻ ions
What is the difference between strong and concentrated?
Strong = how easily it dissociates
Concentrated = how much is dissolved.
What is a type of indicator?
Litmus paper
What is a supersaturated solution?
Type of unstable solution with more solute than saturated
How does temperature affect dissolving rate?
It speeds up dissolving by making particles move faster.
Why is ammonia considered a base
Because it accepts H⁺ ions in solution.
What is the difference between weak and strong acids
Strong acids ionize almost completely, weak acids only partly ionize.
What are two products formed in a neutralization reaction
