acid basics
The Arrhenius definition of an acid.
What is a substance that produces H 1+ ions in water solution.
This is the Arrhenius definition of a base.
What is a substance that produces OH1- ions in aqueous solution?
This is the type of chemical reaction that occurs in an acid/base titration.
What is a neutralization reaction?
If solution A has pH 6, and solution B has pH 4, this is the one that is the more acidic.
What is solution B (pH 4)?
These are the two products in an acid/base neutralization reaction.
What are salt (an ionic compound) and water?
Aqueous is the term for this type of solution.
What is a solution in which the solvent is WATER?
This is the name for the OH1- ion.
What is the hydroxide ion?
The long glass tube used to deliver drops or acid or base in a titration has this name.
What is a buret?
When the amount of H 1+ ions in a solution increases, the amount of this type of ion goes down proportionately.
What is the oH1- or hydroxide ion?
This is the name for HNO3.
What is nitric acid?
This is the name for the H3O 1+ ion.
What is hydronium ion?
Common strong bases have metal ions from these two groups on the periodic table.
What are Group I and Group II?
This is the name for the indicator used in our titration experiments.
What is phenolphthalein?
Every single number jump on the pH scale means that amount of H1+ has changed by this factor.
What is 10 (or 10-fold)?
This (formula) is the "conjugate base" for HNO3.
What is the nitrate ion, NO31-?
This is the Bronsted definition of an acid.
What is a proton donor?
This is the definition of a Bronsted base.
What is a proton acceptor?
This was the property of our acid samples that was "unknown" in both of our titration experiments.
What is: how many mols (or how many molecules) of acid were in our sample?
This would be the pH of a solution that has 1000 times as much OH1- as a solution at pH 8.
What is pH 11?
The conjugate acid for water is this ion.
What is hydronium ion, or H3O1+?
This is the meaning of "strong acid".
What is an acid that ionizes completely in aqueous solution (when it is dissolved in water).
These are the formula and the name for the only weak base we have mentioned in class.
What is NH3, ammonia?
The base used in both of our titration experiments was 1.0 M NaOH. This is the meaning of M.
M means molarity, or mols of base in 1 liter of the solution.
This is the meaning of "neutral pH".
THIS is the full balanced chemical equation, reactants and products, for the reaction of magnesium hydroxide (Mg(OH)2 and hydrochloric acid (HCl).
What is:
Mg(OH)2 + 2 HCl __ > MgCl2 + 2 H2O ?
