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 is commonly used natural indicator?
natural indicators can be used to detect whether a given substance is an acid or base.It can be easily available in our homes too. And you can prepare it too.They do not have harmful affects .so they should be used instead of chemical indicator which may some time be harmful.
Why shouldn't i wear contact lenes during chemirsty labs even if wearing goggles?
Gases or fumes produced during a chemical reaction can literally melt your contact lens onto your eyeballs. You're just putting yourself in a riskier situation to wear contact lens during labs, even if you're wearing goggles. Think about it.
How are individual DNA strands are constructed?
DNA replication duplicates the DNA strands. This process is accompanied by various enzymes such as DNA polymerase, Helicase, Topoisomerase.In labs they are constructred by Polymerase chain reaction(PCR).
Ap bio lab 1?
You can receive all 12 AP Biology labs at apanswers.webs.com. They have a whole year's worth of AP Biology labs. I used the site last year to pass AP Biology and the AP exam at the end of the year. It'll only cost 14 bucks, but it's well worth it because they get the labs straight from the Collegeboard handbook.
What is phenolphthalein used in titration labs?
Phenolphtalein is an indicator used to find the endpoint of a reaction (specifically an acid-base reaction). It has a pH range of 8.3 to 10.0 which means it can be used for a strong acid to strong base titration or a weak base to strong acid titration. Phenolphthalein is clear when it is in the presence of acid and pink when it is in the presence of a base.

What are the different types of labs?
There are various types of labs including research labs where scientific experiments are conducted, clinical labs for medical testing, forensic labs for analyzing evidence, computer labs for technology experimentation, and teaching labs for student education. Each type of lab serves a specific purpose and employs different methodologies and equipment.
What is the benefit of a titration?
As you are using different indicators and you will be knowing either the acid's or base's pH,so it helps in understanding the science behind the pH.As you can find now,whether your area water has some stagnate water mixed with it or not could be determined by you,Instead of going to any government labs or technologies.It is something practical and the other is it is the basic and important step to start chemistry.
What is the Male Labrador head structure?

What is Volumetric Buret used for in labs?
A burette is a volumetric measuring glassware which is used in analytical chemistry for the accurate dispensing of a liquid, especially of one of the reagents in a titration. The burette tube carries graduated marks from which the dispensed volume of the liquid can be determined.
What are the industrial uses of titrimetry?
Volumetric titrimetry is an entry-level method of chemical analysis using volumes of solution with known titer (concentration) to determine the concentration of an unknown substance, or analyte. Used in industrial chem-labs and teaching labs across the world, volumetric titration is widespread in use due to theinexpensive materials needed, the technical ease of the measurement, and the straightforward interpretation of the result.
