Properties of Bases
This ion (OH-) is produced when a base dissolves in water. What is its name?
Hydroxide
This stron base is used in drain cleaner and releases lots of OH- ions
Sodium hydroxide (NaOH)
Electricity applied to salt water produces NaOH, Chlorine gas and this gas
Hydrogen Gas
A salt is made from the positive ion of a base and he negative ion of this
What is an acid
Salts of sodium, potassium and this ion are always soluable
Ammonia Ion NH4+
Acit + Base ------> Salt + _____
Water
What color litmus paper do you use to test for bases and what color does it turn. Two answers needed.
Test = red
Result = blue
This weak base is found in window cleaner and only partially ionizes
Ammonia (NH3) - - NOT Ammonium Hydroxide (NH₄OH)
Heating calcium carbonate (limestone) produces CaO and this gas
Carbon Dioxide CO2
The reaction that forms salt + water is called this
Neutralization Reaction
Most salts containing this negative ion (NO-3) dissolve easily
Nitrates
In the reaction H+ + OH- the product is this neutral molecule
Water
This texture explains why bases feel like soap. They are ______________
slippery
Baking Soda is a weak base because it releases only a few of these ions
Hydroxide ions
Adding water to CaO produces this base used in cement and plaster
Calcium hydroxide Ca(OH)2
In HCL + NaOH these ions are the "leftovers" that form NaCl - - - be specific - two answers
Na+ and Cl-
This chloride (AgCl) is a classic example of an insuluable salt
Silver Chloride
The ions Na+ and Cl- are called this because they don't react
Spectator ions
Unlike acids, bases DO NOT react with _______ to produce hydrogen gas
metals
Strong bases can do this to skin inf not handled carefully
burn
This process (one compound ---> smaller pieces) describes CaCO3
What is this reaction called
Decomposition reaction
These ions appear on both sides of the equation and do not participate - what are they called
Spectator ions
Most salts containing this ion CO2-3
do not dissolve in water
Carbonates
Neutralization "neutralizes" because H+ and OH- do this to each other
This word is another word for "base" and describes substances with pH above 7
Alkaline
This formula explains why ammonia doesn't fully break apart in water
NH3+H2O ---->
<------- NH4+ + OH-
What tye of reaction is this called?
Reversable Action
This base is produced industrially and used to make soap, paper and plastics
Sodium hydroxide (NaOH)
When a salt solution evaporates, these remain behind
Salt crystals
Whether a salt dissolves or not depends on these charged particles that are simply called ______-
ions
The salt formed when HCl reacts with NaOH is called what
Sodium Chloride NaCl
