Título: Determination of chlorides in water (Mohr Method)
Descripción: Se valora en el laboratorio la cantidad de cloruros presentes en aguas de riego utilizando el Método de Mhor Soriano Soto, MD. (2018). Determination of chlorides in water (Mohr Method). hdl.handle.net/...
Descripción automática: In this video, the instructor demonstrates a practical lesson in determining the concentration of chloride in a water sample using Mohr's method. The process involves a chemical reaction where chlorides form silver chloride. The video guides viewers on the step-by-step procedure, including the point where a pinkish-red precipitate signifies the end of the reaction.
The necessary materials and reagents are listed, such as a burette, burette stand, Erlenmeyer flasks, acetic acid, sodium carbonate, distilled water, and potassium chromate indicator. The instructor emphasizes the importance of the pH level, specifying that it should be adjusted between 6.3 and 10.5 using sodium carbonate or acetic acid depending on the initial pH.
The titration process involves adding silver nitrate drop by drop while continuously shaking the flask until the appearance of the pinkish-red precipitate. The video concludes with instructions on how to record the volume of silver nitrate used, which is essential for calculating the chloride ion concentration in the sample. The specific formula to apply for the calculation is mentioned as an integral part of the lesson.

1:56 - Potassium chromate, not potassium dichromate.

Is that really gr/l Cl or did you mean g/l Cl? And what do you mean Factor Agno3 pls clarify I'm confused

[@user-he6ow2dq1q]

Very clear very simple.. Thank you for this explanation

[@kannonwarren4517]

you prolly dont give a damn but does anybody know of a way to get back into an Instagram account?
I stupidly forgot my password. I would appreciate any tips you can give me.

@Trevor Luciano thanks so much for your reply. I found the site through google and I'm in the hacking process atm.
I see it takes a while so I will reply here later when my account password hopefully is recovered.

[@kannonwarren4517]

@Trevor Luciano it did the trick and I now got access to my account again. I'm so happy!
Thank you so much, you saved my account :D
