The solution was diluted to 250 mL in a volumetric flask to obtain a solution for standardizing the EDTA titrant. 1. What is the molar A 0.4505g sample of CaCO_3 was dissolved in HCl and the resulting solution was diluted to 250ml in...
It consists of a mixture of eosin (an acidic stain), and Methylene blue (a basic stain) in Methyl alcohol and is usually diluted and buffered during the staining procedure. What is eosin Azure? Eosin Azure (EA 36), also known as Papanicolaou stain, is a counterstain used to differentiate...
How to Prepare 5M HCl in the Lab The most common reason you will need to handle HCl is when you prepare 5M HCl for your lab to adjust the pH of solutions. Let’s go through how to do this. Firstly, here are a few facts:
You have 100 mL of a 12 M solution of HCl, and you need to dilute it to 1.5 M for an experiment. How many liters will your new solution be? How many mL of a 3.19M solution must be diluted to 1.24L to make a 0.204M solution?
The secondary antibody may also be diluted in blocking solution or wash buffer. If not denoted differently by the manufacturer you can start with a dilution of 1:200 and incubation for 1 h at room temperature. It is necessary to carry out the incubation steps in darkness to prevent fluoro...
In a fume hood place the sapphire disks in concentrated hydrochloric acid (HCl 30%) for 2 h. Wash the sapphire disks 3x for 5 min with doubly distilled (dd) H20. Let the sapphire disks dry on filter paper afterwards. After the cleaning process, a finder grid pattern needs to be ev...
Describe how to make 2.5 L of 0.1 M HCl solution from 12 M HCl concentrated solution and water. How would drought conditions impact infiltration and condensation from the ground? What effect does outside pressure have on the boiling point of water? Why does the detergent sodium dodecyl-sulfate...
Calculate how much glucose is needed to make 500 mL of a 5% glucose solution. Solutions: In chemistry, a solution is created by dissolving a substance *the solute) in another substance (the solvent). For example, when we mix table salt (NaCl) with water, we are effect...
