Acids And Bases Test Flashcards
What is a solution with its weak acid and it’s conjugate base
Buffer
Which system is responsible for buffering our blood every day
Carbonic acid or bicarbonate buffer system
What will our blood do if our pH has dropped to low
Acidosis
Occurs during acidosis
Increased amount of H plus ions and pair up with bicarbonate ions
What is alkalosis
Alkalosis 0H- ions are paired with carbonic acid ions to lower a higher PH
Can lungs due to compensate for acidosis
Hyperventilate
What can the kidney do to decrease acidosis
Decrease HC03- output
What can the lungs due to solve alkalosis in the blood
Hypoventilation- retains CO2 in the blood
What can the kidney do to compensate for alkalosis
Produce less HCO3 minus prevent its reaction with H plus
What is a neutralization reaction
And acid can react with a base to produce a salt and water
What is an indicator
Substances can be identified as acids or bases when they are tested with an indicator changes color based on a solutions pH
What is phenolphthalein
An indicator that is pink in basic solutions and clear an acidic solutions
What is bromothymol blue
Indicator that is blue and basic solutions and yellow in acidic solutions
What is H30 plus also known as
The hydronium ion
What is OH minus also known as
The hydroxide ion
What will doctors tell you to eat if you need to neutralize excess stomach acid and why
Antacid because it’s a weak base
Any ionic compound can also be called a
Salt
What do usually think of when we say the word salt
Sodium chloride
This substance can donate protons
Acid
This substance can except protons
Base
What are Bronsted Lowry acids and bases
Acids that donate protons and bases that accept protons
What is a conjugate acid base pair
They differ by just one proton where the acid has the extra proton
How are H plus and OH minus related
Are inversely related because H plus times OH minus equals 1×10 to the -14th
How are pH and POH related
They are inversely related because pH plus P0H equals 14
What would have a lower pH?
1.00 M solution of HCl?
1 M solution of HCH302
The HCl solution because it is a stronger acid
Why would KOH have a higher pH then NH3
Because KOH is a stronger base
What does HCl produced when it Ionizes in water
Hydrogen ions
If a solution is highly acidic that it will have a very high concentration of
Hydronium ion
Which of the following is the correct chemical formula formula for nitric acid
HNO3
What is the correct name for Ba(OH)2
Barium hydroxide
Name the following acid HCLO2
Chlorous acid
A substance reacts vigorously with metals and conduct electricity well what type of substance is this
A concentrated strong acid
Which of the following applies to a solution with a pH of 4
It has a hydroxide ion concentration of 1×10 to the -10th
Conducts electricity
Both acids and bases
It reacts with metals
Acids
What type of solution would have the greatest concentration of hydroxide ions
Dilute strong base
To write the equilibrium expression what should you never add
A solid or a liquid
What is a buffer
A solution that resists change in pH
Binary compound acids end in what
Ic
Ternary compounds (3 elements) end in what
Ic
Compounds that end in Ite
Ous
Hydrogen nitrate becomes
HNO2
Nitrous acid
What is purpose of an acid-base indicator in titration
To determine the endpoint
Name example of a Bronsted Lowry base
NH3
Name an example of an Arrhenius base
KOH
If the value of equilibrium is less than one minute favors what
The reactants
If the value of the equilibrium is more than one then it m favors what
Products
What is an arehnius base definition
Substance that produces OH in water
Does endpoint or equivalence point mean
When the acid and base neutralize each other
Wendy phenolphthalein indicator turned a faint pink color
When the moles of H plus equals the moles of OH minus
Does endpoint or equivalence point mean
When the acid and base neutralize each other
Wendy phenolphthalein indicator turned a faint pink color
When the moles of H plus equals the moles of OH minus
