1
Q

mixture

A

combination of two or more substances that are not chemically combined

2
Q

salt

A

ionic compound that forms when a metal atom replaces the hydrogen of an acid

3
Q

electrolyte

A

substance that dissolves in water to give a solution that conducts an electric current ex. salt

4
Q

non-electrolyte

A

substance that doesn’t ionize when dissolved, are polar-covalent/covalent

5
Q

neutralization

A

reaction of the ions that characterize acids and the ions that characterize bases to form water molecules and a salt

6
Q

hydroxide ion

A

OH, in bases

7
Q

hydronium/ hydrogen ion

A

H, in acids

8
Q

indicator

A

compound that can reversibly change color depending on conditions such as pH

9
Q

dissolve

A

to break down into a liquid

10
Q

dissociate

A

cation and anion get surrounded by water and pulled apart, breaking atoms and ions into smaller forms

11
Q

weak acid

A

are partially ionized in water

12
Q

strong acid

A

fully ionize in water

13
Q

dilute

A

small amount of solute, a lot of water

14
Q

concentration

A

the amount of a solute that can be dissolved in a given amount of solution

15
Q

homogenous mixture

A

mixture that looks the same

16
Q

heterogeneous mixture

A

mixture that looks different

17
Q

solution

A

a homogeneous mixture throughout which two or more substances are uniformly dispersed

18
Q

acid

A

react with water to make hydronium and an anion, HAS H IN EQUATIONS, reacts w metals to make salt and hydrogen, reacts with bases to make salt and water, sour taste, are electrolytes, litmus paper=red

19
Q

base

A

dissociate in water to make hydroxide and a cation, HAS OH IN EQUATIONS, becomes less basic when mixed w acids–> makes salt and water, soapy, are electrolytes when dissolved in water, litmus paper= blue

20
Q

pH

A

value that is used to express the acidity of a system, pH of 7= neutral, less than 7= acidic, more than 7= basic

21
Q

polar

A

anything that dissolves in water, structure all looks the same

22
Q

non-polar

A

anything that doesn’t dissolve in water, structure isn’t unifrom

23
Q

solute

A

in a solution the substance that dissolves in the solvent

24
Q

solvent

A

in a solution the substance in which the solute dissolves, present in the greatest amount in volume

25
Q

concentrated

A

large amount of solute, little water

26
Q

weak base

A

are partially dissociated in water

27
Q

strong base

A

strong bases are fully dissociated in water
