What is the method to calculate the pH at the equivalence point for a titration involving a strong acid and a weak base?
To calculate the pH at the equivalence point for a titration involving a strong acid and a weak base, you can use the formula pH 7 (pKa of the weak base). This is because at the equivalence point, the solution contains only the conjugate acid of the weak base, which determines the pH.

Titration involving bismuth sulfate and Titration involving mercuric nitrate?
Titration involving bismuth sulfate would typically be used to determine the concentration of a solution of a known or unknown substance that can react with bismuth ions. On the other hand, titration involving mercuric nitrate would be suited for determining the concentration of substances that can react with mercuric ions. Each titration method is specific to the ions involved and the chemical reactions occurring.
How do you do the titration of aluminium alloy?
To perform a titration of an aluminum alloy, you can use a suitable titrant like sodium hydroxide (NaOH) to titrate the solution containing the alloy. The endpoint of the titration can be determined using a pH indicator or potentiometric method, where the equivalence point corresponds to the complete reaction of aluminum in the alloy with the titrant. By measuring the volume of titrant consumed at the endpoint, you can calculate the concentration of aluminum in the alloy.
What is acid titration?
Acid titration is a method used in analytical chemistry to determine the concentration of an acid in a solution. It involves gradually adding a standardized solution of base (titrant) to the acid solution until the equivalence point is reached, indicated by a color change in the indicator solution or pH meter. This helps calculate the unknown concentration of the acid.
Why in Mohrs method of titration pH is maintain as neutral?
In Mohr's method of titration, the pH is maintained as neutral in order to ensure that the indicator used in the titration changes color sharply at the equivalence point. This helps in accurately determining the end point of the titration, as the color change will be clearly visible when the reaction is complete. Maintaining a neutral pH also prevents any interference from acidic or basic impurities that could affect the accuracy of the titration.
What is the method used to carry out an investigation to study the pH changes that take place when neutralisation reactions occur between two named acids and a named base?
To study the pH changes during neutralization reactions between acids and a base, you would typically set up a titration experiment. In this method, a base with a known concentration is slowly added to an acid of unknown concentration until a neutral pH is reached. By monitoring pH changes throughout the titration process, you can determine the equivalence point and calculate the concentration of the acid.

Determination the concentration of concentrated hydrochloric acid?
To determine the concentration of concentrated hydrochloric acid, you can perform a titration with a standardized solution of a base, such as sodium hydroxide. By carefully adding the base to the acid solution and monitoring the pH change using a pH indicator or a pH meter, you can identify the equivalence point and calculate the concentration of the acid using the volume and molarity of the base solution used in the titration.
Detect equivalence point in titration without an indicator?
Titration without indicator is only possible with another measurement:Examples / possibilities:pH-electrode measurement (acid-base titration)Conductivity measurement (acid-base titration or ion-reaction)Change of color by excess or depletion of the reactant/titrant (redox titration)Precipitation by excess or depletion of the reactant/titrantAdded:(The following was more or less written for 'indicator' titrations, but same principles count for other 'sharply' changing properties):The equivalence point is the point where the number of moles of titrant equal the number of moles of the reactant. The end point is the point where the indicator being used changes color (also 'indication point)'.If the indicator is chosen correctly, the end point will essentially be as near as possible at the equivalence point.The point of the titration is to find the equivalence point -- the end point is just a very close approximation to it. This is because the pH of the solution changes very rapidly close to the equivalence point.Therefore, the indicator will change color very close to the equivalence point because of the steepness of the pH change
Describe a method to visually detect the end point of a titration without the use of instruments?
The method used most often in chemistry labs is by use of a pH indicator in the sample being titrated. When you reach the titration point, the indicator will change colors, demonstrating the end point of the titration.
What are the disadvantages of conductometric titration?
Disadvantages of conductometric titration include potential interferences from impurities or ions in the sample, difficulty in detecting equivalence points accurately, and the sensitivity of the method to changes in temperature and electrode conditions. Additionally, conductometric titration may not be suitable for samples with low conductivity or nonionic compounds.
Why use double indicator in titration?
Using a double indicator in titration can provide more accurate results because different indicators change color at different pH levels, allowing for a more precise endpoint determination. This method helps to identify a narrower range where the titration is most effective, resulting in a more accurate determination of the equivalence point.
