It will cause the culture to become more basic...an increase in pH
The pH of urea agar after hydrolysis is around 8-9. Urea is hydrolyzed by urease-producing bacteria to form ammonia and carbon dioxide, raising the pH of the agar medium. This increase in pH is often used as a diagnostic test to identify urease-positive organisms.
The pH of a freshly prepared solution of urea is around 7, which is considered neutral. However, urea can hydrolyze over time to form ammonia and carbon dioxide, which can increase the pH of the solution.
The hydrolysis of salt can affect the pH of buffer solutions by either increasing or decreasing it. When a salt undergoes hydrolysis, it can release ions that can either react with water to produce acidic or basic solutions, thus impacting the pH of the buffer solution.
Acidic hydrolysis uses an acid to break down chemical compounds, while alkaline hydrolysis uses a base. Acidic hydrolysis typically results in the formation of an acid and alcohol, while alkaline hydrolysis results in a salt and alcohol. The choice between acidic and alkaline hydrolysis depends on the specific compound being treated and the desired reaction products.
The pH of a 0.1M solution of AlCl3 would be quite low due to the hydrolysis of aluminum ions in water, leading to the formation of H+ ions and acidic conditions. The exact pH value would depend on the equilibrium constants for the hydrolysis reactions involving aluminum ions.

The stability of aqueous urea is affected by pH because urea can undergo hydrolysis in alkaline conditions, leading to the formation of ammonia and carbon dioxide. In acidic conditions, urea is more stable due to lower hydrolysis rates. Therefore, maintaining a neutral pH is important for the stability of aqueous urea solutions.
After hydrolysis of urea in urease agar, the pH typically increases, resulting in an alkaline environment. This occurs because urease enzyme converts urea into ammonia and carbon dioxide, with ammonia raising the pH. As a result, the medium may change color, usually to pink, indicating a pH shift to above 7.0.
Urea water solution is neutral.

The pH of a milk sample will go down due to carboylate anions. The hydrolysis is performed with triacylglycerols to glycerol.
During sugar fermentation, bacteria consume sugars and produce organic acids as byproducts. These organic acids decrease the pH of the culture medium by increasing its acidity due to the release of protons. As a result, the pH of the medium becomes more acidic over time.
Complete hydrolysis of chromosomal nucleic acids gave inorganic phosphate, 2-deoxyribose and four different heterocyclic bases
The pH of a 0.1M solution of AlCl3 would be quite low due to the hydrolysis of aluminum ions in water, leading to the formation of H+ ions and acidic conditions. The exact pH value would depend on the equilibrium constants for the hydrolysis reactions involving aluminum ions.
It is urease positive .It possesses the enzymes urease which hydrolyses urea to form ammonia. As a result the pH of the medium used for detection of urease enzyme (Urea Broth) increases and shows bright pink colour, since phenol red is bright pink in alkaline conditions.
