Final answer:
Amorphous phosphates are found in alkaline urine. The presence of monobasic phosphates in urine makes it more alkaline in nature. The pH of urine can also be affected by the time of intake of food.
Step-by-step explanation:
Amorphous phosphates are found in alkaline urine. The presence of monobasic phosphates in urine makes it more alkaline in nature. The pH of urine can also be affected by the time of intake of food, as urine collected immediately after food shows an alkaline nature due to the liberation of HCO3 ions into the blood. Acid-forming diets, such as non-vegetarian diets with protein-rich foods, can make the urine acidic, while base-forming diets, such as vegetarian diets, can make the urine alkaline.
