Without the specific details, one cannot be sure, but this is probably a back titration. You add a known amount of acid to your unknown, then titrate to measure how much has not reacted. You can then calculate how much of your first chemical must have been present.

Can a blank titration reading be greater than sample titration?
yes.
Why is the milk cooled before the bacteria are added?
Because it is. face it
How many molecules are present in 0.340g of HCl?
0,34 g HCl contain 5,6.10e21 molecules.
How is plastic dyed?
Before the plastic is molded dyes are added to the molten plastic.
What does HCL in clonidine hcl 0.1 mg mean?
Clonidine is a drug that is used to treat attention deficit hyperactivity disorder (ADHD) and hypertension. Clonidine HCl is the hydrochloride salt of Clonidine (the free base), and it is more soluble in water than ins the free base. The 0.1 mg is the usual oral dose.
Why is HCl added for the titration of vitamin C?
HCl is added to adjust the pH of the solution, making it more acidic and promoting the conversion of ascorbic acid (vitamin C) to its oxidized form, dehydroascorbic acid, which is easily detectable by the titration method used to quantify vitamin C content.
Why was HCL added for the titration f Vitamin C?
Hydrochloric acid (HCl) is added to the titration of vitamin C to acidify the solution and provide a suitable acidic medium for the reaction between vitamin C and iodine to occur. The acid helps in the oxidation of ascorbic acid (vitamin C) by iodine, which is essential for determining the vitamin C content accurately through titration.
What is nature of titration curve obtained in titration of hcl against naoh?
The titration curve obtained in titration of HCl against NaOH is a typical acid-base titration curve. It shows a gradual increase in pH at the beginning due to the addition of base (NaOH). At the equivalence point, the curve shows a sharp increase in pH since all the HCl has been neutralized. After the equivalence point, the pH continues to rise as excess NaOH is added.
Problems faced in carrying out HCl to Na2CO3 titration?

What are the precaution steps in during titration?
Ensure that all glassware and equipment are clean and dry before starting the titration. Use a calibrated burette to accurately measure and deliver the titrant into the analyte solution. Perform a rough titration to determine an approximate endpoint before carrying out the actual titration. Record the volume of titrant added at the endpoint accurately to calculate the concentration of the analyte.
Why is Volume of HCl used for blank titration is more than volume of HCl used for oil titration?
The blank titration is used to determine the exact amount of acid needed to neutralize any impurities in the titration setup, such as the indicator and solvent. This additional volume of acid is accounted for in the blank titration and is subtracted from the volume of acid used in the titration with the oil sample.
Why use h2so4 instead of hcl in titration of kmno4?
H2SO4 is typically used instead of HCl in the titration of KMnO4 because HCl can react with KMnO4 and form chlorine gas, which can interfere with the titration results. Additionally, H2SO4 provides the required acidic medium for the reaction to occur between KMnO4 and the analyte.
Why we can not use HNO3 and HCL for creating acidic medium in this titration?
HNO3 and HCl cannot be used together to create an acidic medium in a titration because they will react and form a precipitate of AgCl, which interferes with the titration. It is important to choose a suitable acid that will not interfere with the reaction being studied in the titration.
Why does HCl not used to acidify the media in potassium permanganate titration?
HCl is not used to acidify the media in potassium permanganate titration because it can react with potassium permanganate, which can interfere with the titration results. Sulfuric acid is usually preferred as it does not react with potassium permanganate and ensures accurate titration results.
Is methylorange the indicator used in the titration of Na2CO3 against HCl solution?
Methyl orange is not commonly used as an indicator in the titration of Na2CO3 against HCl solution. Phenolphthalein is a suitable indicator for this titration because it changes color in the pH range of the equivalence point.
Is the indicator generally added to the titrant or the analyte in a titration?
The indicator is typically added to the analyte in a titration. It helps to visually signal the endpoint of the titration by changing color as the reaction progresses.
Is the indicator generally added to the titrant or analyte in a titration?
Analyte is the indicator that is generally added in titration.
