STARTER

Your first challenge is to identify the different types/theories of acids and bases! This will pick out the tools we will use in the kitchen.

Arrhenius acids/bases focuses on:

Generating [OH-] in solutions

Donates [H+] & [OH-] in solutions

Donating [H+] in solutions

Nothing

Accepting [electron] lone pair in solutions

the sour taste

Generating [H+] & [OH-] in solutions

Bronsted-Lowry emphasizes:

[OH-] generated in solutions

Donating [H+] in solutions

Nothing

Accepting [electron] lone pair in solutions

the bitter taste

[OH-] taking electrons

[H+] & [OH-] donated in solutions

Lewis Acid/Base focuses on:

[OH-] generated in solutions

Donating [OH-] in solutions

Everything

the sweet taste

[H+] taking electrons

[H+] & [OH-] donated in solutions

Accepting & donating [electron] lone pairs

YUMMY !

MAIN COURSE

Your second challenge is to read and identify the characteristics of acids, bases, and neutral. Consider where can we find them.

Acid, Base or neutral with the following characteristics?

Acid

Characteristics:

• Produce H+ (H3O+) in water as the only positive ion.
• Acids are electrolytes. They ionize and conduct electricity in water. ex. HCl(aq)
• Dilute quantities taste sour. ex. Citric Acid
• Corrodes metals to produce hydrogen gas (H2)
• Concentrated Acids are CAUSTIC, they cause chemical burns to skin.
• Turn Blue Litmus Red
• Phenolphthalein turn colorless
• Neutralizes Bases
• pH less than 7

Neutral

Base

Acid, Base or neutral with the following characteristics?

• Produce OH- in water
• Taste bitter, chalky
• Electrolytes
• Feel slippery, like soap
• React with acid to form salt and water
• pH greater than 7
• Turns red litmus blue

DESSERT

Your third challenge is to "NEUTRALIZE" the sour and bitterness!

Which combination can neutralize ?

AgNO3 + NaCl → NaNO3 + AgCl

HCl(aq) + LiOH(aq) → HOH(ℓ) + LiCl(aq)

Na+ + Cl- → NaCl

Which combination can neutralize ?

H2SO4(aq)+KOH(aq)→H2O(ℓ)+K2SO4(aq)

C2(g)+O2(g)→CO2(g)

C3H8(g)+5O2(g)→4H2O(ℓ)+3CO2(g)

Select the combination for neutralization to take place :

Strong acid

Only weak acid

Strong base, weak acid

Salt, strong acid

salt, water

Strong base, Strong acid

Base, salt

water, base

Weak base, strong acid

(There is more than one possible combo, try to identify them all!)

DRINKS

Your last challenge is to identify solutions as acids, bases, and neutrals based off of the given pH!

WATER: pH 7

Acid Neutral Base

Milk: pH 6.5-6.7

Acid Neutral Base

Soda: pH ~3

Acid Neutral Base

Gatorade: A substance is classified as an electrolyte because:

It contains ionic bonds

Its aqueous solution conducts an electric current

It has a high melting point

Its aqueous solution has a pH value of 7
