Chapter 3, Problem 3.4QAP

5.61 x 10^-12 is the ksp

Use the following atomic masses (in g/mol): K = 39.1; Mn = 54.94; O = 16; H = 1; P = 30.97; C = 12.01; Na = 23; Mg = 24.31; S = 32.06; Zn = 65.38; Cu = 63.55 In the standardization of Hydrochloric Acid against pure anhydrous Sodium Carbonate, 1mL was found to be equivalent to 0.05g of the primary standard. Compute for the normality of the acid.

Please 4 and 5!

Ksp = 1.5x10^-11 for Mg(OH)2

1a.  List THREE (3) advantages of internal standardization method than normal calibration.

I want the answer in j not in kj

Please solve for questions 1-8 using the given data, show your work.

Is this correct? refer to the red numbers and words. Thanks in advance!

I need help calculating these values make sure they are 3 sig fig!!!
