In a titration of a sample of HCl(aq) with 0.113 M NaOH(aq), it took 51.2 mL of the base to reach the endpoint of the titration. Calculate the number of moles of the acid being neutralized. Is titration qualitative or quantitative?
To determine the equivalent weight of NaOH, first it needs to be determined what type of substance it is. NaOH is a base; therefore, the n number of equivalents is the absolute value of the number of hydroxide ions. In this case, there is 1 hydroxide ion that dissociates in water. ...
Calculate the pH of a 1.0 L acetate buffer that is 2.0 M in acetic acid and 2.0 M in sodium acetate after the addition of 0.20 moles of NaOH. {eq}(K_a = 1.8 \times 10^{-5}) {/eq} Buffer Solution: A ...
Molar Mass of HCl: 36.46 g/mol ElementSymbolAtomsMass % Hydrogen H 1 2.8% Chlorine Cl 1 97.2% Step 2 Multiply the volume of the standard solution of NaOH by its concentration to determine the number of moles of the titrant used for the titration. Number of moles=Volume (in L) x mol...
It is a compound that is produced by neutralizing nitric acid with ammonia. The chemical formula of ammonia is {eq}NH_4NO_3 {/eq} that is otherwise written as {eq}N_2H_4O_3 {/eq}. It is a highly soluble crystal solid that is used as the fertilizer....
Molarity (M) = (moles of solute) ÷ (liters of solution). To calculate the number of moles of a solute, you need two pieces of information, which you may have to infer from other data. The first is the chemical formula of the solute, and the second is the mass of the solute. Yo...
Follow the stoichiometry - how many moles of NaOH reacted? I'm not sure I'm sorry I thought 1.It would be easier if you'd just explain the solution for me and I would understand it that way.Thanks It's better in terms of your learning if you come to the solution your self. What...
What mass of NaOH is required to create 500 mL of a 0.4 M solution of Sodium Hydroxide(aq)? Determine the number of moles of NaOH required to neutralize the acetic acid in the 100.0 mL of vinegar. Approximately what mass of sodium hydroxide is needed to react ...
Calculate the[OH−]in an aqueous solution with[H+]=6.8×10−8M. Question: Calculate the[OH−]in an aqueous solution with[H+]=6.8×10−8M. Self-Ionization of Water: The self-ionization equilibrium of water is an acid-base reaction of two water molecules to create hydroniu...
What indicator should be used for titration? What is conductometric titration in analytical chemistry? In a titration of a sample of HCl(aq) with 0.113 M NaOH(aq), it took 51.2 mL of the base to reach the endpoint of the titration. Calculate the number of moles of the acid being neutral...
