100

This property of an acid distinguishes them from bases when tasted in dilute solutions.

What is a sour taste?

100

Acidity or alkalinity (basic-ness) is quantified by this value.

What is pH value?

100

A substance that dissociates in solution to form ions and conducts electricity

What is an Electrolyte?


100

Titration utilizes this type of chemical reaction.

What is the neutralization reaction?

100
At a pH of 5.6 phenolphthalein will be

What is colorless?

200
This test produces hydrogen gas only for acids

What is reactivity with a metal?

200

Acidic solutions have a pH in what range?

What is 1-6?

200

All Arrhenius acids have this ion

What is H+/hydrogen ion.

200

When the hydroxide and hydrogen ion concentrations are equal in a titration.

What is the end point.

200

In this pH range Methyl Orange is red

What is 3.1 and below?

300
Both alcohols and bases have a hydroxide group. This property of bases distinguishes them from alcohols.
What is Conductivity (electrolyte)?
300

This ion increases in solution when the pH of a solution increases

What is the hydroxide ion? (OH-)

300

All but one base in Table L is Arrhenius, NH3. Ammonia is not Arrhenius because it lacks this ion

What is the hydroxide ion, OH-

300

In a titration, 5.0 mL of a 2.0M NaOH(aq) solution exactly neutralizes 10.0 mL of HCl(aq). The concentration of HCl(aq) is

What is 1.0 M

300

Both Methyl Orange and Bromothymol blue are yellow in this pH range

What is 4.4-6.0?

400

Both acids and bases form this in solutions which is why they can conduct electricity.

What are ions?

400
This change in hydronium ions would decrease a pH value by 2. 

What is 100 times increase hydronium ions?

400
In the following equation, water is a Bronstead-Lowry base because it accepts this ion.

H+ + H2O --> H3O+

What is the hydrogen ion/a proton?

400

This volume of 0.120M HNO3(aq) is needed to completely neutralize 150.0 mL of 0.100M NaOH(aq)

What is 125 mL?

400

Thymol blue will turn from blue to yellow when this substance is added

What is an acid?

500

Acids and bases participate in this type of chemical reaction

What is a neutralization reaction?

500

What is the new pH of a solution if the starting pH was 7 and the hydronium concentration becomes 1000 times greater?

pH = 4

500

Ammonia is a base because it accepts a proton due to this feature creating a coordinate covalent bond.

What is a lone pair?

500

This many moles of HF are needed to neutralize 250mL of 3.00M NaOH. 

What is 0.75 moles?

500

A solution is tested and turns phenolphthalein pink, and thymol blue yellow. Another substance is added until the phenolphthalein is colorless. What color is the thymol blue?

Yellow
