What else can I help you with?
What substance would you add to NaHCO3 to form a buffer solution?
You could add a weak acid or a weak base to NaHCO3 to form a buffer solution. Examples of substances that could be added include acetic acid (CH3COOH) or ammonia (NH3). Buffer solutions help resist changes in pH when small amounts of acid or base are added.
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.
What can be mixed in solution with H2CO3 to make a buffer?
A weak acid or its conjugate base can be mixed in solution with H2CO3 to make a buffer. Suitable options could be sodium bicarbonate (NaHCO3) or a weak acid like acetic acid (CH3COOH).
Why you have to add buffer before titration with EDTA?
Adding a buffer solution before titration with EDTA helps to maintain a constant pH which is crucial for the formation of metal-EDTA complexes. The buffer solution prevents any fluctuations in pH that could affect the accuracy and precision of the titration results.
Why buffer AP1 and AW1 concentrate may form white precipitate upon storage?
The formation of white precipitate in buffer AP1 and AW1 concentrate upon storage could be due to the presence of insoluble salts or impurities in the buffer components. These salts can come out of solution over time as the buffer solution sits, leading to the formation of a precipitate. It is important to ensure that all buffer components are fully dissolved and that the solution is properly stored to prevent this issue.

Could a mixture of pepper and water could be a solution?
No because pepper is not solution in water. Thank You
How do you make this solution?
I don't know how to make the solution below. Low salt buffer: 10 mM phosphate buffer, 10 mM NaCl, pH 7.4. Could you tell me the method in detail?
What can be mixed in solution with H2CO3 to make a buffer?
A weak acid or its conjugate base can be mixed in solution with H2CO3 to make a buffer. Suitable options could be sodium bicarbonate (NaHCO3) or a weak acid like acetic acid (CH3COOH).
Substance that causes a solution to resist changes in pH?
A buffer is a substance that helps a solution resist changes in pH by neutralizing added acids or bases. Buffers typically consist of a weak acid and its conjugate base, or a weak base and its conjugate acid, allowing them to maintain the pH of a solution within a certain range.
What is the of the resulting solution?
The resulting solution could be a homogeneous mixture, a heterogeneous mixture, a compound, or a suspension, depending on the substances being mixed and their interactions.

Are all solution mixture are all mixture solution?
Not all mixtures are solutions and vice versa. A mixture could be spaghetti and bolognese but that isn't a solution because nothing dissolves in to the other thing. A tablet in water is a solution because the tablet dissolves.
You maked phosphate buffer white pH 8.5 and then store in refrigerator and become crystallin why?
The crystallization of the phosphate buffer solution could be due to the formation of insoluble salts precipitating out of the solution, which can occur over time when stored in the refrigerator. This could be caused by the presence of impurities in the buffer components or changes in temperature. To prevent crystallization, try filtering the solution before storage to remove any insoluble particles and ensure that the buffer components are fully dissolved before use.
What is the antonym of solution?
Solution: Solving a problem, dealing with a difficult situation, or the correct answer.Some antonyms are problem, trouble and question.Solution: A liquid mixture of two or more substances.Some antonyms are chemical and element.
