The total hardness of the water sample is calculated as 37.64 ml of 0.01 M EDTA solution. The calcium hardness is calculated as the difference between the total hardness and the magnesium hardness, which is 29.32 ml of 0.01 M EDTA solution. It's important to conduct proper titration techniques to ensure accurate results for water quality assessment.

Why water may be added after the acid has been pipetted in?
Adding water after the acid can help to dilute the acid in a controlled manner, minimizing any splashing or spattering that may occur if water were added to the acid. This step also allows for better mixing of the acid and water to ensure uniformity in the solution.
How much grams can a pipette hold?
Pipettes come in various sizes and types, so the volume they can hold is usually measured in milliliters (mL) rather than grams. The maximum volume a pipette can hold depends on its size, with common sizes ranging from 0.1 mL to 25 mL. The weight of the liquid in the pipette would depend on the density of the liquid being pipetted.
What is the formula for titration?
The formula for titration involves the stoichiometry of the reaction between the analyte and titrant. It typically follows the equation: n(A)V(A) = n(B)V(B), where n represents the number of moles, V is the volume, and A and B refer to the reactants involved in the titration.
What is used to identify acids and bases?
Acids and bases can be identified using indicators, pH paper/strips, pH meters, or by measuring the pH using a pH scale ranging from 0 to 14. Acids typically have a pH below 7, bases have a pH above 7, and neutral substances have a pH of 7.
What is a buret used for?
A burette, or buret, is a uniform-bore glass tube with fine gradations and a stopcock at the bottom, used especially in laboratory procedures for accurate fluid dispensing and measurement.The buret is commonly used in titrations to measure precisely how much liquid is used.(see related links)

Does serum contain DNA?
Serum is generally free from blood cellular components but when collecting serum sometimes few cells will be pipetted with the serum & that is the only source of DNA in the serum.

What effect does temperature have on the precision of the pipette?
Temperature can affect the volume delivered by a pipette due to changes in the density of the liquid being pipetted. Warmer temperatures can decrease the liquid's density, causing it to expand and potentially result in lower volume delivery, while cooler temperatures can increase density, leading to higher volume delivery. It is important to account for temperature variations and calibrate pipettes accordingly to ensure precision.
How do you use centrifuge to separate plasm in blood?
To separate plasma from blood using a centrifuge, the blood sample is first collected in a tube. The tube is then placed in the centrifuge and spun at high speeds, causing the blood components to separate based on their density. Plasma, being the lightest component, will rise to the top of the tube, allowing it to be easily pipetted off and collected for further analysis.
