The short version: Urine can be either basic or acidic, depending on your hydration levels.

Urine pH is used to classify urine as either a dilute acid or base solution. Seven is the point of neutrality on the pH scale. The lower the pH, the greater the acidity of a solution; the higher the pH, the greater the alkalinity. The glomerular filtrate of blood is usually acidified by the kidneys from a pH of approximately 7.4 to a pH of about 6 in the urine. Depending on the person's acid-base status, the pH of urine may range from 4.5 to 8. The kidneys maintain normal acid-base balance primarily through the reabsorption of sodium and the tubular secretion of hydrogen and ammonium ions. Urine becomes increasingly acidic as the amount of sodium and excess acid retained by the body increases. Alkaline urine, usually containing bicarbonate-carbonic acid buffer, is normally excreted when there is an excess of base or alkali in the body. Secretion of an acid or alkaline urine by the kidneys is one of the most important mechanisms the body uses to maintain a constant body pH. A highly acidic urine pH occurs in: * Acidosis * Uncontrolled Diabetes * Diarrhea * Starvation and dehydration * Respiratory diseases in which carbon dioxide retention occurs and acidosis develops A highly alkaline urine occurs in: * Urinary tract obstruction * Pyloric obstruction * Salicylate intoxication * Renal tubular acidosis * Chronic renal failure * Respiratory diseases that involve hyperventilation (blowing off carbon dioxide and the development of alkalosis) In people who are not vegetarians, the pH of urine tends to be acidic. A diet rich in citrus fruits, legumes, and vegetables raises the pH and produces urine that is more alkaline. Most of the bacteria responsible for urinary tract infections make the urine more alkaline because the bacteria split urea into ammonia and other alkaline waste products. The urine pH varies in different types of acidosis and alkalosis. Control of pH is important in the management of several diseases, including bacteriuria, renal calculi, and drug therapy. The formation of renal stones is related to the urine pH. Patients being treated for renal calculi are frequently given diets or medications to change the pH of the urine so that kidney stones will not form. Calcium phosphate, calcium carbonate, and magnesium phosphate stones develop in alkaline urine; when this occurs, the urine is kept acidic. Uric acid, cystine, and calcium oxalate stones precipitate in acidic urine; in this situation, the urine should be kept alkaline or less acidic than normal. Drugs such as streptomycin, neomycin, and kanamycin are effective in treating urinary tract infections if the urine is alkaline. During treatment with sulfa drugs, alkaline urine helps prevent formation of sulfonamide crystals. Here are important points to remember about urinary pH: * During sleep, decreased pulmonary ventilation causes respiratory acidosis. As a result, a first waking urine specimen is usually highly acidic. * Bacteria causing a urinary tract infection or bacterial contamination will produce alkaline urine. * A diet rich in citrus fruits, most vegetables, and legumes will keep the urine alkaline. * A diet high in meat and cranberry juice will keep the urine acidic. * Urine pH is an important screening test for the diagnosis of renal disease, respiratory disease, and certain metabolic disorders.

When it's fresh it's acidic but becomes basic when the moisture evaporates and leaves urine crystals behind.
im not sure
Acidic
Urine contains uric acid and hence, is acidic.
blood or urine but Blood would be a better answer
Crystals in the urine are probably uric acid, although there are other possibilities such as oxalic acid. Crystals are not negative or positive, they are neutral. An ionic compound is composed of both positive and negative ions, which add up to a neutral compound.
Correct answer:Sugar is neutral, neither acid nor base: there are no protolysiable H atoms.Redirected:So you can NOT say : "Sugar is an acidic substance"The next part is not validated by any logic:"Studies have shown that people who consume more of sugar and items made from it, have a more acidic urine." There are more possibillities to get acidic urine.
The pH of urine is close to neutral (7) but can normally vary between 4.5 and 8. Strongly acidic or alkaline urine may be symptomatic of disease

pure water is neutral with a pH of 7
Urine is definitly an acid. Vunerable elements do react to Urine. The average urine takes the coloring of (yellow.) Depending on the person, the potency of the acid varies. The average strength is a bit above Vinegar.

Urine is naturally slightly acidic, as of its color, yellow. By drinking a nearly completely neutral substance, it begins to make it neutral. Water is not completely a perfect 7, but can be anywhere between 6.8 and 7.3 on the pH scale.
Urine is normally shightly acid in the fasting state... Neutral of somewhat alkaline for an hour or so following a meal. There is nothing wrong with those results...

Ever body part has a different pH. The pH of blood should be 7.4. The pH of gastric acids in your stomach is 2-3. The pH or urine is around neutral 7.
