Here is a link to the make up of buffers from 1 to 13 . Scroll down for the pH 13 range, http://delloyd.50megs.com/moreinfo/buffers2.html ph 13 buffer needs to use Sodium Hydroxide. You can only get to pH 10 with Ammonia. Ammonia is only a 'weak' base to get to pH 13 you need a 'strong ' base ,strong bases are the Hydroxide's of Sodium, Potassium or other alkaline metals. Here is a link that explains the concept of weak and strong base's http://en.wikipedia.org/wiki/Base_(chemistry)
To make an ammonia buffer at pH 13, mix ammonia solution (NH3) with its conjugate acid, ammonium hydroxide (NH4OH), in a ratio that will give you the desired pH. Typically, the ratio is about 10:1 of ammonia to ammonium hydroxide. Use a pH meter to adjust the ratio until you reach the desired pH of 13.
Buffer ammonia is used in water total hardness tests to maintain a stable pH level during the titration process. The presence of ammonia helps prevent fluctuations in pH that could affect the accuracy of the hardness test results.
The pH of aqueous ammonia depends on its concentration, with higher concentrations leading to a higher pH. In general, the pH of an ammonia solution will be alkaline, typically ranging from 11-13. The pounds of ammonia per gallon of water will affect the concentration and thus the pH of the solution.
Sodium acetate buffer is a commonly used buffer solution in biochemical and molecular biology laboratories. It consists of a mixture of sodium acetate and acetic acid, and helps maintain a stable pH when added to solutions. It is effective in the pH range of around 4.7 to 5.7.
To prepare a phosphate buffer of pH 7.5, you can mix appropriate amounts of monosodium phosphate and disodium phosphate in a ratio that will achieve the desired pH. Adjust the pH using either phosphoric acid or sodium hydroxide, depending on whether you need to increase or decrease the pH. Make sure to use a pH meter to accurately adjust the pH to 7.5.
To prepare an acetate buffer at pH 3.5, mix acetic acid and sodium acetate in the appropriate proportions to achieve the desired pH. First, calculate the ratio of acetic acid to sodium acetate needed using a buffer calculator or handbook. Then, mix the calculated amounts of acetic acid and sodium acetate in the required volume of water and adjust the pH to 3.5 using a pH meter or pH indicator.
Buffer ammonia is used in water total hardness tests to maintain a stable pH level during the titration process. The presence of ammonia helps prevent fluctuations in pH that could affect the accuracy of the hardness test results.
A commonly used buffer for pH 12-13 is a mixture of potassium hydrogen phthalate and sodium hydroxide. This combination helps maintain a stable pH in this alkaline range. Alternatively, a borate buffer system can also be used for pH around 12-13.
To make a borate buffer, mix boric acid with sodium hydroxide or sodium borate in water. Adjust the pH of the buffer to your desired range by adding more acid or base. Remember to use a pH meter to accurately measure the pH of the buffer.
Ammonium chloride (NH4Cl) could be added to an ammonia solution to form a buffer solution. As ammonia accepts a proton (H+) to form ammonium ion (NH4+), the ammonia-ammonium ion pair acts as a buffer system, maintaining a stable pH.
The pH of aqueous ammonia depends on its concentration, with higher concentrations leading to a higher pH. In general, the pH of an ammonia solution will be alkaline, typically ranging from 11-13. The pounds of ammonia per gallon of water will affect the concentration and thus the pH of the solution.
Ammonia solution is a basic compound that can be used to increase the pH of a solution. It can act as a buffer to help stabilize the pH, especially in biological and chemical processes where maintaining a specific pH range is important. Ammonia solution can also be used in various applications such as cleaning and as a nutrient source in agriculture.
To buffer a solution with a pH of 12, you would need to add a weak acid and its conjugate base in appropriate amounts. This will help prevent drastic changes in pH when an acid or base is added to the solution. Common buffer systems for a pH of 12 could involve using a weak base like ammonia (NH3) and its conjugate acid ammonium chloride (NH4Cl).
The buffer maintain the pH constant.
Household bleach has a pH around 12-13, making it basic, while household ammonia has a pH of around 11-12, also making it basic. However, bleach is more alkaline than ammonia, making it a stronger base.

Sodium acetate buffer is a commonly used buffer solution in biochemical and molecular biology laboratories. It consists of a mixture of sodium acetate and acetic acid, and helps maintain a stable pH when added to solutions. It is effective in the pH range of around 4.7 to 5.7.
No, a buffer does not always hold the pH of a solution at pH 7. A buffer is a solution that can resist changes in pH when an acid or base is added. The actual pH at which a buffer solution can effectively resist changes depends on the specific components and their concentrations in the buffer system.
