Acids and Bases
This type of solution contains H+ ions
What is an acid.
this table is part of the chemistry reference table and is used to identify indicators
what is table M
There are two different forms of calculating concentration of solutions
what is molarity and parts per million
name the laboratory pieces of equipment necessary to complete a titration experiment
What are a burette, flask and clamp stand
What is a salt and water.
This solution contains a high amount of hydroxide ions
What is a base.
This indicator turns RED at a pH of 5
What is litmus paper
calculate the molarity of 14.2 g of NaNO3 (molar mass = 85.0 g/mol) in enough water to make 350 mL of solution
What is 0.477 M
This indicator is normally used for a titration. It begins colorless and turns pink when the equivalence point is obtained
What is phenolphthalein
These can be used to identify if a reaction is neutralized
What is pH paper and litmus paper.
The scientists Arrhenius stated that acids and bases are defined as
what is an Acid is a proton/hydrogen donor while Bases are hydrogen acceptors.
These make up the mixture of a solution. One is in a smaller quantity while the other is in a larger quantity to do the dissolving
What is solute and solvent
if 0.02 gram of NaCl is dissolved in 1000. grams of solution what is the concentration in parts per million?
what is 20 ppm
If it takes 50 mL of 0.5 M KOH solution to completely neutralize 125 mL of sulfuric acid solution (H2SO4), what is the concentration of the H2SO4 solution?
What is 0.2 M
Complete the equation for this neutralization reaction:
KOH (aq) + HCl (aq) -->
What is KCl (aq) + H2O (l)
The pH scale is used to identify the potential of hydrogen in a solution. If a solution goes from a pH of 4 to a pH of 2, the tenfold concentration would be
what is 100 times stronger
This indicator is used for titration when neutralizing an acid. It changes color between pH 8-9
What is phenolphthalein
Based on Table G, what is the mass of KCl that must be dissolved in 200. grams of H2O at 10.°C to make a saturated solution
What is 60 g
A student completes a titration by adding 12.0 milliliters of NaOH(aq) of unknown concentration to 16.0 milliliters of 0.15 M HCl(aq). What is the molar concentration of the NaOH(aq)?
What is 0.20 M
This occurs when H+ reacts with OH- in aqueous solution
What is neutralization.
This is describe as ions dissolved in water
what is an electrolyte
name the two types of mixtures and how they are different
what is homogenous and heterogenous mixtures. Homogenous components are not seen with the naked eye while heterogenous components of a mixture can be seen
Compared to the freezing point and boiling point of water at 1.0 atm, a 0.5 M aqueous solution of NaCl at 1.0 atm has
what is a lower freezing point and a higher boiling point
Titration is a method/technique used for what pupose
What is neutralize a reaction and determine the concentration of an unknown substance
These two scientists worked independently and identified the same acid base theory
