Which of the following solutions will have the highest concentration of chloride ions?
a)0.10 m nacl
b)0.10 m alcl3
c)0.10 m mgcl2
d)0.05 m cacl2
e)all of these solutions have the same concentration of chloride ions.

B = 0.10 M of AlCl₃

Explanation:

A = 0.10 M NaCl

NaCl → Na⁺ + Cl⁻

sodium chloride dissociate into sodium and chlorine ions. The one mole of NaCl produced on mole of Na⁺ and one mole of Cl⁻, so concentration of chloride ions will be 0.10 M.

B = 0.10 M of AlCl₃

AlCl₃  →    Al³⁺ + 3Cl⁻

AlCl₃ dissociate into aluminium cation and chlorine anion. one mole of AlCl₃ dissociate into one mole of Al³⁺ and three mole of Cl⁻.

so concentration of chloride ion in 0.10 M solution is

0.10 × 3 = 0.3 M

C = 0.10 M MgCl₂

MgCl₂   → Mg²⁺ +  2Cl⁻

MgCl₂ dissociate into one mole of Mg²⁺ and two mole of Cl⁻.

so concentration of chloride ions in 0.10 M solution of MgCl₂ is,

2× 0.10 M = 0.20 M

d = 0.05 M CaCl₂  

CaCl₂  →   Ca²⁺ +  2Cl⁻

CaCl₂ dissociate into one mole of  Ca²⁺ and two mole of Cl⁻, So concentration of chloride ions in 0.05 M CaCl₂ is

2× 0.05 = 0.1 M

when—without warning—something provokes your anger, you may struggle not to succumb to it. since what typically makes you mad is feeling powerless in the face of what seems unfair, your anger is mostly an attempt at a “quick fix” to right the balance. it’s as though you’re raising a fist in protest, proclaiming that you’re not going to capitulate to such injustice.

there are, however, a multitude of problems related to this immediate, push-back reaction of anger. and probably the key one is that almost never does it resolve the issue that gave rise to it. such reactive anger is probably best understood as self-defeating. as david burns, the author of the seminal self- book feeling good, observes: if realistically, acting on your anger is to make any sense, it needs to meet two criteria—which, in almost every case, is frankly impossible. that is, your anger must:

be directed toward a person who has intentionally (and needlessly) behaved in a hurtful way toward you; and

be beneficial or advantageous to you (i.e., assist you in achieving a desired goal).

i think you’ll agree that only rarely can you claim that your anger is both warranted and , whether to yourself or the relationship.

so let me offer you a two-step alternative to abandoning your better judgment and giving in to the temptation of anger—one that should neutralize your anger in seconds. or, when you’re really angry, in minutes.

but keep in mind that you must really want to execute these steps, be sufficiently motivated to perform them. which means overcoming more unconscious resistance than you might ever have imagined. because there are many immediate “advantages” of anger that can interfere with your resolve, i’ll suggest a few of them that might interfere with your employing this powerful method to rid yourself of counter-productive anger.
