For each solution, identify as Weak Electrolyte, Strong Electrolyte or Non-Electrolyte. 0.25 M K 2 SO 4 0.056 M HNO 3 0.123 MNH 3 0.124 MC 6 H12 O 6 The last IV bag in stock of 'Potassium Solution' has listed on it 154 mEq/L of Potassium Chloride. If you wanted to make another IV bag, how many grams ot potassium chloride would you have to add to make a 100 mL solution? What is the pH of a 0.0217M HCl solution? (HCl is a strong acid) Balance the following neutralization reactios. Provide the products with correctExplanation / Answer
17)
a) strong electrolyte
b) strong -electrolyte
c) weak electrlolyte
d) non electrolyte
19) given 154 meq/L of KCl
given 100 ml
normality = equivalent x 1000/ volume (ml
normality = mass x 1000/ equivalnet weight x volume
eqivalnet weight of KCl is 74.55
154 x 10-3 = mass x 1000/ 74.55 x 100
mass = 1.148 g
so 1.148 g of KCl should be added .
20) Given 0.0217 M Hcl
pH =-log [H+]
As HCl is a strong acid .
[H+] = [HCl]
pH =-log 0.0217
pH = 1.66
so the pH is 1.66
