A solution is prepared that has 10^-3 M NaCl (s) and 10^-3 M Ca(OH)2 (s). (20 Pts) a. What is the ionic strength of solution if both salts are completely dissolved. b. We know that Ca(OH)2 (s) is in fact sligthly soluble. What is the ionic strength of solution if 30% of added Ca(OH)2 (s) has dissolved and 90% NaCl (s) has dissolved. c. What is the concentration of NaCl (s) before any dissolution occurs? = 0.5
