How to Make a Volumetric Solution for Titration

A comprehensive step by step guide for sodium hydrogen sulfate titration and preparation of volumetric solutions for accurate concentration determination in acid-base reactions.

  • The practical demonstrates how to make a volumetric solution for acid-base titration using sodium hydrogen sulfate (NaHSO4) and sodium hydroxide (NaOH)
  • The experiment utilizes phenolphthalein as an indicator which changes from pink/purple to colorless at the endpoint
  • The process involves precise measurements, careful solution preparation, and multiple titrations to calculate concentration in a chemistry titration experiment
  • Safety considerations and proper handling of corrosive materials are emphasized throughout the procedure
  • The method requires careful attention to detail in measurements and calculations to ensure accurate results

Part 3: Titration Procedure and Data Collection

The detailed titration procedure explains the step-by-step process of determining the unknown concentration.

Highlight: Multiple titrations are performed to ensure accuracy, with the first serving as a rough estimate.

Definition: The endpoint is reached when a permanent color change occurs, indicating complete neutralization.

The process includes careful measurement of 25.0cm³ of sodium hydroxide solution and systematic addition of sodium hydrogen sulfate while monitoring color changes.

View

Part 4: Calculations and Safety Considerations

This section focuses on the mathematical aspects of determining concentration and important safety protocols.

Highlight: When calculating the mean volume, the first rough titration and any outlying results are excluded.

Example: Titrations must be within 0.1cm³ of each other to be considered valid for calculations.

The risk assessment portion emphasizes the hazardous nature of the chemicals used:

Part 1: Introduction and Solution Preparation

This section outlines the fundamental setup for preparing an accurate volumetric solution for titration analysis. The reaction between sodium hydrogen sulfate and sodium hydroxide is explained, along with the role of phenolphthalein indicator.

Definition: A volumetric solution is a precisely concentrated solution used for quantitative chemical analysis.

Example: The reaction equation demonstrates the process: NaHSO4 + NaOH -> Na2SO4 + H2O

Highlight: Phenolphthalein serves as the indicator, changing from pink/purple to colorless at the endpoint.

The equipment list includes essential items such as a volumetric flask, weighing boat, digital balance, and various measuring tools needed for precise solution preparation.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Brad T

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀
