Acids
The pH of an acid
What is 1 - 6.99
The pH of a base
what is 8 - 14
The pH of water
What is the equation for molarity?
what is 1 mol / 1 L
The color that acids will change on litmus paper
What is red or orange
The thing an acid likes to do with hydrogens
What is donate them
The thing a base likes to do with hydrogen
What is accept them
The two things formed from every acid/base reaction
What is water and salt
The amount of liters (L) in a 2M solution
What is 1 L
The color bases will turn on litmus paper
What is green or blue
Select all of the acids in the list below:
HCl, LiOH, H2SO4, Mg(OH)₂
What is HCl and H2SO4
Select all of the base in the list below:
HF, HCO3, KOH, Ba(OH)₂
What is KOH and Ba(OH)2
If I mix together 40 grams of HF into 1L of water, then what would the molarity (M) of the solution
What is 2M
The amount of mols in a 3M solution
What is 3 mols
What is because of a different in hydrogens present in the solution
One of the three chemicals that when they react with water will create acids that are often found in our atmosphere or oceans.
What is NO2, SO3, or CO2
(These will create HNO3, H2SO4, and H 2CO3
The substance that is often found in kitchens that is perfect for putting out grease fires.
What is baking soda
(1 HCl + 1 NaOH -> 1 H2O + 1 NaCl) The pH that is resulted from mixing together equal amounts of of a 1M NaOH solution with a pH of 8 and a 1M HCl solution with a pH of 1
What is a pH of 7
(1 HCl + 1 NaOH -> 1 H2O + 1 NaCl) The amount of a 2M NaOH solution I would need to use to neutralize an 50 mL of a 1M HCl solution.
What is 25 mL of the NaOH
(1 HCl + 1 NaOH -> 1 H2O + 1 NaCl) The color that will result in a mixture of 40 mL of a 2M HCl solution and 25 mL of a 4M NaOH solution if the color turns yellow when acidic and red when basic.
What is red
The reason why an acidic ocean results in calcium based organisms decomposing
What is an equilibrium shift.
The addition of acids will create more H+ ions then what is natural. This results in the CO3- molecule to react with the H+ resulting in the molecule that supports the Calcium based materials to go away.
(Half points to "It reacts it away") Which is technically correct but not as detailed as will be necessary on the test.
Mixing together these two things will create soap because of this process.
What is oil and a base (Lye/NaOH) and through the process of saponification (The base breaking down the fatty acid tails)
(1 HCl + 1 NaOH -> 1 H2O + 1 NaCl) The pH that is resulted from mixing together equal amounts of of a 2M NaOH solution with a pH of 14 and a 2M HCl solution with a pH of 6
What is a pH of 7
The amount of sodium hydroxide (NaOH) you would need, with 1 L of water, to make a 3 M solution.
What is 120 grams of NaOH
The pH level that would be the titration or equilibrium point if I am using a pH indicator that will go from clear to purple depending on the pH.
What is a pH of 7
