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
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...

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 themass of ...
How do you find initial Ph of an acid-base titration? How to choose an indicator for an acid-base titration? What is a redox titration in chemistry? How to calculate the molarity of a solution In a titration of a sample of HCl(aq) with 0.113 M NaOH(aq), it took 51.2 mL of the ...
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...
Calculate the pH of asparagine with dissociation constant Ka = 9.55 x 10^-3 and CM = 0.300 mol/L. 1. Explain how to identify the concentration of vinegar in an experiment. 2. Explain how to calculate the molarity of acetic acid ( H C 2 H 3 O 2 ). ...
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.
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 ...
So, find the moles of sodium carbonate, and then double it to get the moles of acid needed. Moles Na2CO3 = 0.03945 Moles HCl needed = 0.03945 x 2 = 0.0789 moles HCl needed Now, if you are actually asking how to find the molarity (M) of the HCl used, then you have....
