The pH scale ranges from 0 to 14 under usual conditions and measures the acidity of an aqueous solution. This is derived from the molarity of protons (hydrogen ions, or H+) in the solution. To find pH for a given molarity, you need to know how to work wi
Find the temperature at which the molarity of pure water is equal to its molality. A 0.186-M solution of X (Mm= 181 g/mol) has a density of 1.027 g/ml. What is the molality of X in the solution? Calculate the molality of a 2.90 M NaCl solution with a density of 1.12 g/mL. ...
Ph.D. University Professor with 10+ years Tutoring Experience About this tutor › Depending on how the concentration is stated, there are different ways to convert to molarity (M). For example if the concentration is given as grams / ml (g/ml), we would first convert the g...
How do you find the concentration of a base in titration? How to calculate moles of NaOH used in titration How does potentiometric titration work? What is the titration formula? What does titration determine? How to calculate molarity of HCl from titration ...
Imagine the lab scenario with some arbitrary values:You have a beaker with a measured 10mL of HCl (unknown Molarity) which you weigh the solution as 10g. You need to find out the mass of the solvent.Ultimately, I need to determine the Molarity of the solution but I need the mass of ...
In real life, you can usually look up the density of commons liquids in reference books or online. While the calculation is simple, it's important to cite answer using the correct number ofsignificant digits. Also, pay attention to the units of your answer and make sure they agree with th...
What is acidity? What does pH actually mean? How does a pH meter work? Who invented the pH meter? Find out moreWhat is acidity?Photo: Some acids, such as lemon juice, are perfectly safe to handle; others will burn your skin and can do painful, permanent damage. How can you tell whi...
The pH of a solution is a measure of the hydrogen ions, or protons, present in that solution. Given the molarity and the pH of a solution containing a weak acid, calculate the percentage of the acid that is ionized.
How to find molar mass from titration? What is the molarity of NaOH if it takes 40.0 mL of NaOH to reach the equivalence point in a titration with 50.0 mL of 0.2 mol/L HCL? (A: 0.25M) The point in a titration where the moles of acid are ...
Attached is data from a chem lab. You have to find the standard deviation of the data. How do you do that when working with percents? Hello, I have a quick question regarding my chemistry homework. I am currently working on stoichiometry and understand it pretty well, but it is always ...
