what is Piston burette or Digital burette
1. what is Piston burette or Digital burette
A burette (also buret) is a laboratory equipment used in analytical chemistry for the dispensing of variable amount of a chemical solution and measuring that amount at the same time. ... Mainly, there are two types of burette which are volumetricburette and Piston burette or Digital burette.
2. What is the difference between a base burette and an acid burette?
Answer:
A burette is a glass tube that has fine gradations and a stopcock at the bottom of it, and is typically used in a laboratory to accurately measure liquids, and to dispense them (hence the stopcock).
Explanation:
3. burette how to measure it
Answer:
Burette reading
In order to measure the amount of solution added in or drained out, the burette must be observed at eye level straight to the bottom of the meniscus. The liquid in the burette should be completely free of bubbles to ensure accurate measurements.
4. Write short note on Mohr’s Scale of hardness with examples
Answer:
Mohr's scale of hardness is a qualitative scale used to measure the hardness of minerals. It was developed by F. Mohr in 1820 and is based on the ability of a mineral to scratch other minerals. The scale ranges from 1 to 10, with 1 being the softest and 10 being the hardest. Examples of minerals on the Mohr's scale of hardness are Talc (1), Gypsum (2), Calcite (3), Fluorite (4), Apatite (5), Orthoclase (6), Quartz (7), Topaz (8), Corundum (9), and Diamond (10).
5. who is manfred mohr?
is considered a pioneer of digital art based on algorithms.
6. Why should the burette be in the analyte solution?
Answer:
You perform titrations to determine the concentration of a chemical in a sample. ... If the concentration of the titrant isn't what you think it is, then your results will be meaningless. Consequently, make sure the concentration of the titrant in the burette is exactly what you expect it to be.

7. 5. Why do you think is the reason why burette is made up of glass?
Answer:
To ensure that there will be no holes that will spill the contents inside
8. what are the differences of burette and pipette
Answer:
Burettes have a stopcock at the bottom while a pipette has a dropper like system that releases liquid in the desired amount by lessening the vacuum. ... As another important difference between burette and pipette, pipettes are more accurate in releasing liquid in smaller quantities than burettes.

10. A student who is standardizing the naoh solution fills the burette with the naoh solution but does not open the stopcock to fill the tip of the burette before starting the titration. will the naoh concentration determined from this titration be higher or lower than the actual concentration
Answer:
efer to Table 1 to identify the major basic ingredients contained in the antacid brands that were titrated. Write equations for the reactions of these three active ingredients with acid, H+.a.Gelusil:i.Al(OH)3+ 3 H+→ Al3++ 3 H2O ii.Mg(OH)2+ 2 H+ → Mg2++ 2 H2O b.Tums:i.CaCO3+ 2 H+→ Ca2++ H2O + CO2(g)3.A student who is standardizing the NaOH solution fills the buret with the NaOH solution but does not open the stopcock to fill the tip of the buret before starting the titration. Will the NaOH concentration determined from this titration be higher or lower than the actual concentration? Explain.a.The concentration will be lower than the actual concentration. It will be lower because the tip of the buret contributes to the concentration of the solution. The tip of the buret also must be filled in order to clean out the buret prior to titration. This is important so the solution is not contaminated with another a previous solution. It will also be lower because not as much NaOH is in the buret, which means less NaOH will go into titrating the solution. Finally, the reading of the buret will also be off because the tip of the buret is accounted for in the reading ofit, and if it is not filled, then the reading will be lower than one is reading on the buret.4.List possible sources of error in this experiment and for each, indicate whether the effect would be an erroneously high or low value for the neutralization capacity of the antacid.a.Part A: Standardization of NaOHi.A few of the steps in the procedure called for CO2free water to be added. If a student did not heat the water correctly, did not cover with a watchglass, or something else that would be a cause for CO2to be in the water still, it could throw the titration off slightly. Depending on the concentration of the CO2in the water, the titration results could vary slightly, or if there is a high concentration of carbon dioxide, it could have a large effect.

Explanation:
14. Directions: Read the statements below, write TRUE if it is correct and FALSE if it is incorrect. __________ 1. The burette should be washed before use and after use. __________ 2. The standard for burette cleaning is that the inner wall of the glass tube does not have water droplets. __________ 3. The burette must be fixed to the titration tube holder for use. __________ 4. When reading the burette, make the burette diagonal and the line of sight should be at the lowest point. __________ 5. During the titration, the eye should look at the change in color in the conical flask, but not the burette. __________ 6. Dropping speed: turn the stopcock and then immediately release the titrant. __________ 7. The last drop just makes a significant change in the color of the indicator and does not restore the original color within 0.5 min. The final volume is read and recorded. __________ 8. Air bubbles in the tip after loading the standard solution into the burette should be removed by vigorously shaking the burette. __________ 9. When performing the titration operation, the burette should be clamped on the titration tube holder. __________ 10. The burette should be inserted into the bottom of the receiving container to make the solution in the container rotate continuously clockwise.
