Here is the step-by-step solution to match the terms on the left with the correct definitions or examples on the right.
Step-by-Step Reasoning:
1.
The acid ion: Acids release hydrogen ions ($H^+$) in water. ->
G. H+
2.
The base ion: Bases release hydroxide ions ($OH^-$) in water. ->
V. OH-
3.
pH value of an acid: Acids have a pH less than 7. ->
F. 0-<7
4.
pH value of a base: Bases have a pH greater than 7. ->
H. >7-14
5.
Neutral pH value: Pure water is neutral with a pH of 7. ->
B. 7
6.
Acid taste: Acids typically taste sour (like lemons). ->
M. Sour
7.
Base taste: Bases typically taste bitter. ->
L. Bitter
8.
Color of phenolphthalein in an acid: This indicator stays clear/colorless in acidic solutions. ->
S. Colorless
9.
Color of phenolphthalein in a base: This indicator turns pink in basic solutions. ->
O. Pink
10.
Technique used to find the unknown concentration of an acid solution: This process is called titration. ->
C. titration
11.
Feels slippery: Bases feel soapy or slippery to the touch. ->
I. Base
12.
Reacts with metals to produce hydrogen gas: This is a characteristic property of acids. ->
Q. Acid
13.
Formed from neutralization: When an acid and base react, they form salt and water. ->
N. Salt and Water
14.
Reaction when the number of H+ = OH-: When these ions balance out, it is called neutralization. ->
E. Neutralization
15.
An example of an acid: Hydrobromic acid ($HBr$) is listed here. ->
U. HBr
16.
An example of a base: Sodium hydroxide ($NaOH$) is a common strong base. ->
T. NaOH
17.
An example of a salt: Sodium chloride ($NaCl$), or table salt, is formed from neutralization. ->
D. NaCl
18.
Color of litmus in an acid: Blue litmus paper turns red in acid. ->
J. Red
19.
Color of litmus in a base: Red litmus paper turns blue in base. ->
R. Blue
20.
Reference table of acids: In chemistry reference tables (like Table K in NYS Regents), acids are listed. ->
P. Table K
21.
pH that is 100X more acidic than a pH of 8: The pH scale is logarithmic. Each step is a factor of 10. To be 100 times ($10 \times 10$) more acidic, you go down 2 steps from 8 ($8 - 2 = 6$). ->
K. 6
22.
pH that is 100X more basic than a pH of 8: To be 100 times more basic, you go up 2 steps from 8 ($8 + 2 = 10$). ->
A. 10
