Why you have to do a titration at least twice?
Since you know how much standard you have used and its concentration you can work out the concentration of the unknown sample.
Remember you should always repeat whole process at least 3 times to ensure you have an accurate result, as there is the potential for both random and systematic errors to affect your results..
What is pH pharma analysis?
The general definition of the pH value of a solution is the negative base-10 log of the concentration of hydronium ion in the solution. In the pharmaceutical industry, we’re used to not more than 1M in concentration under normal cases. With that being said, the pH value could be on 2 extremes in that case.
What is titration in a simple explanation?
Titration, process of chemical analysis in which the quantity of some constituent of a sample is determined by adding to the measured sample an exactly known quantity of another substance with which the desired constituent reacts in a definite, known proportion.
What chemicals are used in titration?
To carry out an accurate titration using dilute hydrochloric acid, dilute sodium hydroxide solution, and phenolphthalein indicator . Titration is a practical technique used to determine the amount or concentration of a substance in a sample. It is an example of quantitative analysis.

Why is universal indicator not suitable for titration?
Originally Answered: Why is a universal indicator not suitable for titration? There is no universsl chemical indicator. There are only chemicals that change color in solution when the pH of the solution changes in a particular narrow range. Therefore one must employ different chemical indicators at different pH ranges.
What is titration in pharmaceutical analysis?
Titration is defined as a common laboratory method of quantitative chemical analysis that is used to determine the unknown concentration of a known reactant. Because volume measurements play a key role in titration, it is also known as volumetric analysis.
What is the importance of titrimetric analysis in pharmaceutical industries?
Abstract. As in many other branches of chemistry, titration has long been one of the standard analytical methods used in the pharmaceutical industry: The analysis (content determination) of active ingredients, drugs and raw materials can be performed easily, quickly, reproducibly and accurately.
Why do chemists use titrations?
A titration is a technique where a solution of known concentration is used to determine the concentration of an unknown solution. … Knowing the volume of titrant added allows the determination of the concentration of the unknown. Often, an indicator is used to usually signal the end of the reaction, the endpoint.
What are the 4 types of titration?
Types of TitrationAcid-base Titrations.Redox Titrations.Precipitation Titrations.Complexometric Titrations.
How is titration used in pharmacy?
Titration is an important part of the analysis in pharmaceutical laboratories and it is used to analyze different raw materials and finished products. … It is a well-known method used in laboratories for the sole purpose of quantitative and qualitative estimation of a particular chemical substance.
What is titration used for in real life?
Titration is used to measure blood sugar levels and to analyze blood for other diagnoses. It’s used to determine pregnancy test results and other types of urinalysis testing. Titration is beneficial in identifying the nutritional breakdown of food values.
What is the role of indicator?
Indicators are substances that are used to test whether a substance is acidic or basic ot neutral in nature. They change their color when added to a solution containing an acidic or a basic substance. … Examples of acid-base indicators include litmus paper, phenolphthalein, and red cabbage juice.
What is end point in titration?
end point: the point during a titration when an indicator shows that the amount of reactant necessary for a complete reaction has been added to a solution.
Which titration is known as Argentometric titration?
The titrations with silver nitrate are known as argentometric titration. This titration is carried out for chloride, cyanide, and bromide ions.
Why is it important to standardize a solution before titration?
The so-called titer determination or standardization of a volumetric solution used for titration is one of the most important preconditions for reliable and transparent titration results. Accurate and reliable titration results are only achievable when we work with the exact concentration of the volumetric solution.
Where is acid-base titration used in industry?
Titration in the Pharmaceutical industry Purity analysis, in which acid-base titrations are often used. A good example is the purity control of the drug ephedrine, found in some cough syrups. An acid called perchloric acid is used as the titrant in this reaction.
