Article: If the dance calls for formal attire, rent or buy a suit and wear a button-down shirt and tie underneath. You can opt for an optional vest or cumberbund under the suit, too. Or go without a jacket altogether and stick with nice dress pants and a button-down for more semi-formal dances. If you’re going with a date, coordinate with them first to see if part of their outfit can match yours. If your date is a girl, their dress, top, or accessories could match your shirt, tie, or vest/cumberbund. Get dress shoes made of leather or similar material. Match them with the color of belt that you’re wearing. Wear a nice leather belt, and choose a watch and a piece of jewelry if you like, such as a ring or a simple necklace. Get cufflinks to fasten the sleeves of your button-down shirt. You can wear a top hat or other dressy hat if you want, but anything like a cap or beanie isn’t acceptable for a formal dance. For a prom or other very formal dance, you can follow the tradition of wearing a boutonniere that complements your outfit and a girl’s corsage. You can tell your date what color to buy you, or you can just buy or make your own! Wear your boutonniere pinned to the lapel of your suit.
Question: What is a summary of what this article is about?
Pick a suit or button-down shirt. Choose the right shoes. Add a belt and other adornments.
Article: Hydrochloric, or muriatic, acid, is a strong, corrosive acid. In high concentrations, it can be used to remove chrome plating from metal objects. For removing chrome, an acid solution of about 30-40% concentration should suffice.  Proceed as below:  Mix 1/3 part hydrochloric acid to 1 part water in a vat used for chemical mixtures (like a heavy-duty plastic bucket, etc.) to produce a 30% acid solution. Alternatively, purchase a pre-mixed acid solution of sufficient concentration. Submerge the chrome-plated object in the solution until chrome strips off. Wash the object thoroughly in soap and water, and rinse before drying. Sodium hydroxide, commonly called lye, is a caustic, highly basic chemical.  It can dissolve several types of metal plating, including chrome, but reacts dangerously with water and aluminum, corroding the aluminum itself and producing flammable hydrogen gas. Thus, it should only be used on items that do not use aluminum as a base material. Proceed as below:  Mix 8 to 12 fl ounces (about 227 ml to 355 ml) of sodium hydroxide with 1 gallon (3.785 L) of water in a vat made of neutral material (like a heavy-duty plastic bucket). Soak the chrome-plated object in solution until chrome comes off. This may take a fairly long time, so frequently check on your item's progress. Wash the object thoroughly in soap and water, and rinse before drying. Chrome is affixed to metal through the process of electroplating, in which electric current is used to bind chrome to the metal at a molecular level. By reversing this process, chrome plating can be removed extremely effectively. However, doing so can be extremely dangerous. Not only does the process involve a live electric current, but also produces several toxic, carcinogenic chemicals as products of the reaction. Hexavalent chromium, for instance, is one extremely dangerous product.  Thus, this process is best left to professionals - the steps below are for informative purposes only.  Mix chromic acid and sulfuric acid in water in an approximately 100:1 ratio. For example, you may add 33 oz. (936 grams) of chromic acid crystals and .33 oz. (9.36 milliliter) of sulfuric acid fluid to distilled water to make 1 gallon (3.79 liter). Mix solution in a proper immersion tank used for electroplating, materials testing, and/or chemical treatments. Heat the solution. Keep the temperature of the solution from 95 to 115 degrees Fahrenheit (35 to 46 degrees Celsius) for decorative chrome. Keep temperature from 120 to 150 degrees Fahrenheit (49 to 66 degrees Celsius) for hard chrome. Run a negative charge from a DC power source through the chromic plating solution via wire. Attach the positive cathode to object intended for stripping and submerge the object into the solution. The positively charged exterior chrome metal will be pulled from the object. Rinse object in agitating running water, then rinse again. Have waste products professionally processed and disposed of.

Use hydrochloric acid (muriatic acid). Use sodium hydroxide (lye) to strip chrome from ferrous metals and carbon steel. Perform a reverse electroplating.
Article: Hibiscus plants grow with terminal flowers; this means that each flower on a hibiscus plant grows at the end of a branch. Pruning a healthy hibiscus bush will encourage growth and tell the plant to grow more branches, thus producing more flowers. You can also prune a damaged or dying tree to prevent future decay and to promote new, healthy growth. Pruning must be timed to line up with the natural growth patterns of the hibiscus plant. You should never prune hibiscus in the late fall or winter, as this will prevent new growth in the Spring. Exact times will vary depending on your location, but generally full/major prunes should be done in the early spring, with minor pruning done up till the beginning of fall around September. If you keep your hibiscus plants inside during the winter, wait until you move them outside to prune. To do damage-free pruning, you'll need to get a very sharp knife, a pair of sharp gardening shears, a pair of sharp lopping shears, and a hand saw for anything too big to be cut with your smaller tools. Sterilize all tools before starting and between pruning each plant, to prevent the spread of disease. You can sterilize with rubbing alcohol, hand sterilizer, or horticultural disinfectant. Your tools must absolutely be sharp; a dull knife, shears, or saw will cause more harm than good if you try to prune with them. Take the time to sharpen your tools, or buy new ones if yours are too old. Keeping in mind that the location you prune is the location of new growth, you always want to prune your hibiscus on branches facing outwards. You'll make all cuts ¼-inch from the top of a node (the location of a leaf/twig) at an upwards 45-degree angle. The lower end of each cut should be near the center of the bush, while the higher end of the cut should be nearer to the outside of the bush. This helps water run off the cut surface instead of pooling, which reduces the risk of infection. Although the amount of the plant that you prune will vary from situation to situation, the general rule is that you should never cut more than ⅔ of any one branch off. Cutting off too much of the plant is no longer considered pruning, but simply damaging the hibiscus.
