The great thing about using w/v is that you don't need to worry about calculating moles of the solute which would require an extra step.Going From W/V to Molarity Say, however, your teacher gives you 21% (w/v) solution of NaCl and asks you to find the molarity of this solution. ...
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 ...
Find the molar equivalent of the hydrogen ion in your acid, and multiply it by the number of moles in the amount of acid added. Since hydrochloric acid has a molar equivalent of 1, you can simply change the units from moles to equivalents. Step 5 Determine the molarity of the hydroxide ...
it's acid I think—you probably learned that useful phrase once upon a time, along with the second half of the same rhyme: "and if it turns blue, it's an alkali true." Measuring acids and alkalis (bases) with litmus paper is something pretty much everyone learns how to do in school...
1.12 g of KHP required 34.38 mL of an approximately 0.3 m NaOH solution in an acid/base titration to reach the equivalence point. What is the exact molarity of the NaOH solution? The equivalence point is the point in a titration at which the added ...
That procedure looks correct, but there are a couple things you need to clarify. That amount of pure diisopropylamine is about 5 mmol. What is the molarity of the n-BuLi that you're using? The mmols obviously need to match. One big pitfall with lithium reagents is that they do go bad...
How to Find Molarity As long as you have a way of measuring the mass of a solute, you can calculate its molarity by measuring the volume of the solution. Be careful here, because molarity is always expressed as moles/liter, so if you measure volume in any other units, you have to con...
Hmm, looks likewe can't plug in the values yet because we don't know the molarity of the H30+, which would have to go in the [H+] spot in the equation.We can find that value using this other equation from the formula sheet: ...
The degree of dissociation can be expressed using the acid dissociation constant (Ka) which also describes the strength of acids. The higher the value of Ka, the stronger the acid.Answer and Explanation: Become a Study.com member to unlock this answer! Create your account View this answer ...
Subpopulations of soluble, misfolded proteins can bypass chaperones within cells. The extent of this phenomenon and how it happens at the molecular level are unknown. Through a meta-analysis of the experimental literature we find that in all quantitative
