The following two experiments are carried out with anhydrous potassium chloride and
observations x and y are made at the end of each experiment.
concentrated sulfuric acid is added to the potassium chloride and the fumes produced are bubbled into aqueous potassium iodide solution - observation x.
the potassium chloride is dissolved in aqueous ammonia and this is then added to aqueous silver nitrate - observation y.
what are the observations x and y?

Observation X: The aqueous potassium iodide solution becomes yellow in color

Observation Y: A clear, colorless solution is observed.

Explanation:

Experiment 1

When Concentrated sulfuric acid is added to potassium chloride, hydrogen chloride gas is produced:

H₂SO₄ + 2KCl ⇒ 2HCl (g) + K₂SO₄

When the HCl gas is bubbled into aqueous potassium iodide, a redox reaction takes place at room temperature when energy is provided in the form of light:

4H⁺ + 4I⁻ + O₂ ⇒ 2I₂ + 2H₂O

The iodine causes the solution to become yellow in color (or darker yellow/brown at high concentrations of iodine).

Experiment 2:

When potassium chloride in aqueous ammonia is added to aqueous silver nitrate, the following net reaction occurs:

Ag⁺ + 2NH₃ ⇒ [Ag(NH₃)₂]⁺

The silver reacts with ammonia rather than chloride as ammonia is a better ligand in this case. The ammonia complex is soluble in water.

Thus, a clear, colorless solution will be observed.

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.
