The Iodine Clock Reaction at Home (Vitamin C Variation)

Today I’ve decided to explore an iodine clock reaction that can be done at home with household materials The general gist of this reaction is that two colorless solutions are mixed and then after a certain period of time a sudden color change occurs There’s a lot of different variations and recipes for the iodine […]

Titration of a weak acid with a strong base | Chemistry | Khan Academy

– Here we have a titration curve for the titration of 50 milliliters of 0.200 molar of acetic acid, and to our acetic solution we’re adding some 0.0500 molar sodium hydroxide. So once again we’re putting pH in the Y axis, and down here in the X axis is the milliliters of base that we […]

Carbohydrate Catabolism Part 4

In this video we are going to discuss what happens to pyruvate following glycolysis. Cellular respiration is defined as the complete oxidation of a glucose molecule to yield energy in the form of ATP. Recall from the Carbohydrate Catabolism Part 2 video, that oxidation is seen as hydrogen ions are stripped from the glucose molecule […]

Acidic amino acids: Protein chemistry

Hello everyone, welcome to today’s presentation where I am going to talk about charged amino acids. So, in this charged amino acids, apart from the amino group and carboxyl group, both are charged at physiological pH, there may be charged side chain or R group. Based on that today we are going to see only […]

How to Speak Chemistrian: Crash Course Chemistry #11

Imagine you wake up one morning, and you’re under a tree, and you don’t recognize anything. You’re surrounded by low, grassy hills. It’s raining a bit and smells like waffles and potatoes. As you rub the sleep from your eyes, you notice a woman, and she’s like “Qu’est-ce que tu fais dans la pluie?” and […]


Valine is an α-amino acid with the chemical formula HO2CCH(NH2)CH(CH3)2. L-Valine is one of 20 proteinogenic amino acids. Its codons are GUU, GUC, GUA, and GUG. This essential amino acid is classified as nonpolar. Human dietary sources are any proteinaceous foods such as meats, dairy products, soy products, beans and legumes. Along with leucine and […]

Strong Acid vs Weak Acid: Comparing Strength of 2 Acids with different pH values

hi guys now I have another question involving ionic equilibria for you so let’s take a look at this question now what we have here are two acids: acid A and acid B now the pH of acid A is one, pH of acid B is three so now the question is which acid is […]
