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)

Why buffer ammonia is used in water total hardness test?
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.
What is the pH of aqueous ammonia in relation to pounds of ammonia per gallon of water?
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?
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.
How do you prepare phosphate buffer of pH 7.5?
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.
How do you prepare acetate buffer pH 3.5?
Dissolve 25g of Ammonium acetate in 25ml of water and add 38ml of 7M hydrochloric acid. Adjust the pH of the solution to 3.5 with either 2M hydrochloric acid or 6M ammonia and dilute with water to 100ml
what buffer has a pH of 8.10?
A buffer with a pH of 8.10 typically consists of a weak base and its conjugate acid. A common example is a solution of ammonia (NH₃) and ammonium chloride (NH₄Cl). This buffer system helps maintain the pH around 8.10 by neutralizing added acids or bases. The specific concentrations of ammonia and ammonium chloride can be adjusted to achieve the desired pH.
Why buffer ammonia is used in water total hardness test?
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.
What can be mixed in solution with NH to make a buffer?
To create a buffer solution using ammonia (NH₃), you can mix it with ammonium chloride (NH₄Cl). Ammonia acts as a weak base, while ammonium chloride provides the conjugate acid (NH₄⁺). This combination allows the buffer to resist changes in pH when small amounts of acids or bases are added, maintaining a stable pH in the solution.
What can be used as a buffer for pH 12-13?
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.
Which compound could be added to an ammonia solution to form a buffer solution?
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.
How do you make a borate buffer?
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.
What is the pH of aqueous ammonia in relation to pounds of ammonia per gallon of water?
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.
What is basic buffer and give an example of it?
A basic buffer is a solution that resists changes in pH when small amounts of acid or base are added, typically composed of a weak base and its conjugate acid. An example of a basic buffer is a solution of ammonia (NH₃) and ammonium chloride (NH₄Cl). In this buffer system, ammonia acts as the weak base, while ammonium chloride provides the conjugate acid, allowing the solution to maintain a relatively stable pH.
What is the role of ammonia solution for pH?
This depends on its concentration. In a 1M ammonia solution (my guess is 17g/L), about 0.42% of the ammonia is converted to ammonium (my guess is 0.07 g/L), equivalent to a pH of 11.63.
How do you buffer a solution that has the pH of 12?
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).
What happens to the buffer a pH capacity?
The buffer maintain the pH constant.
How does the pH of household bleach compare to the pH of household ammonia?
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.
