### Prep for Test 1

Do we need to memorize any Ka or Kb values for Test 1?

No, we do not need to memorize any Ka or Kb values. You should be able to interpret them and/or calculate them though.

You shouldn't have to memorize any values for Ka and Kb, just understand how to work out the formula for each and that Kw=Ka x Kb and Kw=10^-14

Nope just be careful that you use Ka for acids and Kb for bases.

No there are no specific values that you need to memorize. A helpful thing to know however, for the test is how to go from Ka to Kb and how to find the pH and pOH given the values of Ka or Kb.

No all constants are given, just know how to use them.

No, you do not have to memorize any Ka or Kb values because they are not constants. you should know that Ka x Kb = Kw. You should also know how to find Ka when you have Kb or vice versa. You should be able to find the pH and pOH when given the values for Ka or Kb.

You should also know how to convert between pKa, Ka, pKb, and Kb.

No I think that the values will be given, but we should be able to interpret and apply these values :)

No, Kb and Ka values will usually be given somehow; you just need to know how to solve for that value if you happen to be given pKa or pKb instead.

No, Ka and Kb values will be provided. It may be wise however, to be comfortable writing out chemical equations for the dissociation of acids and bases in water.

Does anyone know if we'll be given a periodic table or are we supposed to know some common mass values?? I'm assuming we will be expected to know molar conversions and stuff like that

You need to know how to calculate and convert between the two, but memorizing values is unnecessary.

no need to memorize, only convert between and analyze

You don't need to memorize but should know the differences and converting.

You don’t need to memorize specific values but it will be very helpful to know common equations we have gone over in class!
