What is an acid and base?
An acid base indicator is a substance that changes colour due the PH of the medium in which it is dissolved.
Does glycolysis occur before the preparatory reaction and the citric acid cycle?
Yes, glycolysis occurs before the preparatory reaction (pyruvate oxidation) and the citric acid cycle in the process of cellular respiration. Glycolysis breaks down glucose into pyruvate, which then enters the preparatory reaction to be converted into acetyl CoA and then further metabolized in the citric acid cycle.
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.
When breaking down a monoglyceride what reaction is that?
A monoglyceride is made up of glycerol and one long chain fatty acid, connected to the glycerol by an ester bond. If you break this down to the free fatty acid and glycerol, the process or reaction is known as hydrolysis, or ester hydrolysis.
Show how alanine could be deaminated to give the end-products indicated alanine pyruvic acid of what value is deamination to a microbe?
Alanine can be deaminated by the enzyme alanine deaminase to form pyruvic acid. This reaction involves the removal of the amino group (-NH2) from alanine. Deamination is valuable to a microbe as it provides a source of carbon for energy production through the production of pyruvic acid, which can enter the citric acid cycle or be used in gluconeogenesis.
What is the type of reaction between an acid and alkaline?
The reaction between an acid and an alkali is a neutralization reaction, where the acid and alkali react to form water and a salt. The pH of the solution will become closer to 7 (neutral) as a result of this reaction.
An acid-base titration involves?
An acid-base titration involves slowly adding a solution of known concentration (titrant) to a solution of unknown concentration (analyte) until the reaction is complete. The endpoint is reached when the indicator changes color or the pH reaches a specified value. This allows for determination of the concentration of the analyte.
A reaction occurs when an acid and base combine.?
When an acid and a base combine, they neutralize each other to form water and a salt. This reaction is known as a neutralization reaction. In this reaction, the pH of the solution tends to move closer to 7, which is neutral on the pH scale.
A reaction between an acid and a base is?
It is called an acid-base reaction. The product is called a salt. For example: NaOH + HCl -> NaCl + H2O NaOH is the base. HCl is the acid. NaCl is the salt. H2O is water.
What happens to pH in acid and base reaction?
As soon as the acid of the vinegar and the alkali base of the baking soda mix there is an chemical reaction which occurs when the two chemicals combine, then causing bubbling and or fizzing, plus the after effect of cold liquid
What is the reaction of acid and alkaline solution?
When an acid and alkaline solution are mixed, they neutralize each other, forming water and a salt. This reaction is known as a neutralization reaction. The pH of the resulting solution will be closer to neutral (pH 7) than the original solutions.
How is the buffering of an acid different from its neutralization?
Buffering an acid uses the acid's conjugate base to prevent any major pH changes. ex. HCO3 and NaCO3 form a buffer. Neutralizing an acid changes all of the acid molecules to a salt and water by using a base. The pH of a neutralized acid is 7. ex. HCl + NaOH -> NaCl + H2O
When you add an alkali and acid what happens?
When an alkali (base) and an acid are mixed, they undergo a neutralization reaction where the hydrogen ions from the acid combine with the hydroxide ions from the alkali to form water. This reaction produces a salt as a byproduct. The result is a solution that is closer to neutral pH.
In terms of particles how and why the rate of reaction changes during the reaction of calcium carbonate with hydrochloric acid.?
The chemical reaction goes faster if calcium carbonate is powdered.
What does acid and an alkali together do?
When an acid and an alkali are mixed together, they undergo a neutralization reaction where the hydrogen ions (H+) from the acid react with the hydroxide ions (OH-) from the alkali to form water. This reaction also produces a salt as a byproduct. The result is a solution that is closer to neutral on the pH scale.
What is the reactions of acid and base?
When an acid reacts with a base, they neutralize each other to form water and a salt. This is known as a neutralization reaction. The pH of the resulting solution will be closer to 7, indicating a neutral solution.
What is a buffer reaction?
A buffer reaction is a chemical reaction involving a buffer solution, which resists changes in pH when an acid or base is added. Buffer solutions contain a weak acid and its conjugate base, or a weak base and its conjugate acid, to help maintain the pH of the solution within a specific range.
