What else can I help you with?
How do you calculate how much base to add to increase the pH of the solution?
This depends on what other acids or bases or buffering substances are in solution already, even if pH is neutral!
What is 7ph?
A pH of 7 is considered neutral. It indicates a balance between acidic and alkaline substances in a solution. Water, for example, has a pH of 7.
How will Phenolphthalein help you test for unknown substances?
Phenolphthalein is a pH indicator that changes color in response to different pH levels. By using phenolphthalein, you can determine if a solution is acidic or basic based on the color change it exhibits. This can help you identify unknown substances by comparing the color change with known pH values of different substances.
What do we call substances that change colour depending on the pH of the solution they are?
yes well you dont have to pay at all
What is the initial pH of the solution in the Erlenmeyer flask?
The initial pH of the solution in the Erlenmeyer flask would depend on the specific substances present in the solution. If it is just pure water, the initial pH would be around 7 (neutral). If there are acids or bases present, the pH could be below 7 (acidic) or above 7 (basic), respectively.
Does baking soda raise or lower pH you?
Baking soda, also known as sodium bicarbonate, raises pH levels when added to a solution. It acts as a buffer and can neutralize acidic substances, thereby increasing the overall pH.
What do we call substances that change color depending on the pH the solution they are in?
Substances that change color depending on the pH of the solution they are in are called pH indicators. These indicators often undergo reversible color changes that are used to determine the acidity or alkalinity of a solution.
What is the pH of disodium phosphate?
The pH of disodium phosphate is around 9-9.5. It acts as a buffer in solution, helping to maintain a stable pH level.
Are substances that change color with respect to the acidity or basicity of a solution?
These substances are called pH indicators.
How does pH enter freshwater?
Water will always have a pH. pH is a measure of how acidic or basic a solution is. Intruduction of basic substances such as carbonates will raise pH. Introduction of acidic substances such as carbonic or sulfuric acid will lower pH.
How can one determine the optimal pH level for a solution?
To determine the optimal pH level for a solution, you can use a pH meter or pH strips to measure the acidity or alkalinity of the solution. The optimal pH level will depend on the specific application or desired outcome of the solution. It is important to consider factors such as the properties of the substances in the solution and the intended use of the solution when determining the optimal pH level.
A pH of 2 indicates a(n) .?
A pH of 2 indicates a strong acid solution. Substances with a pH of 2 are highly acidic and have a high concentration of hydrogen ions.
What to do if yiu get corrosive substance on your work surface?
Corrosive substance can be removed with contrasting pH substances. Because corrosive substances are acidic or low on the pH scale, the solution to remove them needs to be high in the pH scale, or basic. Ammonia is an example of a basic solution.
What is the pH of Lysine?
Lysine itself is a neutral compound and therefore does not have a pH value. When lysine is dissolved in water, the pH of the solution will depend on the concentration of lysine and other substances present in the solution.
How do you calculate how much base to add to increase the pH of the solution?
This depends on what other acids or bases or buffering substances are in solution already, even if pH is neutral!
What measures a solution and ability to neutralize acid?
pH measures the acidity of a solution. A solution with a low pH value (0-6) is acidic, a pH value of 7 is neutral, and a pH value above 7 is basic. Substances that can neutralize acids are called bases.
What pH is cobalt chloride?
Cobalt chloride does not have a fixed pH as it is a salt and does not directly determine the acidity or basicity of a solution. The pH of a solution containing cobalt chloride would depend on the concentration of the solution and any other substances present that may affect the pH.
