What else can I help you with?
What will salt solution turn into with universal indicator?
A salt solution with universal indicator will likely show a neutral pH, appearing green in color. This is because salts are typically pH-neutral compounds that do not significantly affect the acidity or alkalinity of a solution when dissolved in water.
What is the pH indicator used in the citrate test?
Bromothymol blue is the pH indicator used in the citrate test. It turns blue at an alkaline pH, indicating that citrate has been utilized by the bacteria.
What is the name of the indicator that gives you the range of colours for different pH numbers?
The indicator that gives you the range of colors for different pH numbers is called universal indicator. It is a mixture of several indicators that changes color over a wide pH range.
What is it called when a substance changes color in response to pH?
This is a pH indicator.
How does a flavin pigment molecule work with a pH indicator?
Flavin pigment molecule can interact with a pH indicator by changing its color based on the pH of the solution. The flavin pigment undergoes a chemical reaction with the pH indicator, leading to a change in its absorption spectrum or structure, resulting in a color change that can be used to determine the pH of the solution.
What colour should sodium sulphate be in universal indicator?
Sodium sulfate is typically colorless in universal indicator. Universal indicator is a pH indicator that changes color based on the pH of a solution, and sodium sulfate is a neutral compound that does not significantly affect the pH.
How do antacids effect a pH indicator?
Antacids work by neutralizing stomach acid, which can change the pH level of the stomach. If an antacid is added to a solution containing a pH indicator, it can affect the color change of the indicator by altering the acidity or basicity of the solution.
What is universal pH paper?
Universal pH paper is a type of indicator paper that changes color based on the acidity or alkalinity of a solution. It covers a wide pH range and can be used to quickly determine the approximate pH of a liquid.
What happens when you mix cornstarch and universal indicator?
When you mix cornstarch with universal indicator, the cornstarch typically does not react chemically with the indicator. Instead, the universal indicator will change color based on the pH of the solution, while the cornstarch serves as a thickening agent. If the mixture is in a solution with a certain pH, the color change of the indicator will reflect that pH level, but the cornstarch will mainly affect the texture rather than the pH itself.
How does an acid affect an indicator?
Acids typically change the color of an indicator by donating a hydrogen ion (H+) to the indicator molecule, altering its structure and causing a shift in color. The specific color change depends on the pH range of the indicator and its chemical properties.
Can an indicator provide an exact pH?
An indicator can provide exact pH if you are using the neutralization titration. Paper strip pH indicator are not an exact measurement but a high, medium, and low indication of acids and bases.
What will salt solution turn into with universal indicator?
A salt solution with universal indicator will likely show a neutral pH, appearing green in color. This is because salts are typically pH-neutral compounds that do not significantly affect the acidity or alkalinity of a solution when dissolved in water.
What fruit and vegetable can you use as a pH indicator?
Red cabbage can be used as a pH indicator for a wide range of pH levels, showing different colors depending on the acidity or alkalinity of a substance. Similarly, beets can also be used as a pH indicator, turning different colors in acidic or basic solutions.
What is the pH indicator used in the citrate test?
Bromothymol blue is the pH indicator used in the citrate test. It turns blue at an alkaline pH, indicating that citrate has been utilized by the bacteria.
What is the color of baking soda on the pH indicator?
Baking soda (sodium bicarbonate) is generally white in color and does not have a specific color on a pH indicator as it is amphoteric, meaning it can act as a base or an acid depending on the context.
What is the name of the indicator that gives you the range of colours for different pH numbers?
The indicator that gives you the range of colors for different pH numbers is called universal indicator. It is a mixture of several indicators that changes color over a wide pH range.
What is the colour of soap on pH indicator?
Soap typically appears pink or red on a pH indicator because it is basic in nature.
