2.5 M HCl solution, but what is found in the stock room is 6.0 M HCl. How much of 1. You were unable to copy your mom's specialty "hinilabos na talangka (salted
crablets) and your guests found it too salty. You prepared it by adding 10% salt
add if your mom said that she prepared her specialty by mixing 20 mL of 0.5% salt
(NaCl) instead?
2. In the laboratory, most reagents are concentrated. Suppose you need 100ml of a
the 6M HCI will you use to prepare 100ml of 2.5 M HCI.?
3. A solution of 96% of H2 SO4 by weight has a density of 1.84g/ml at 25*C.
Find
a. mole fraction
b. molality
c. molarity

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
