Find the moles of NaOH used in a titration reaction with HCl if 3.725 mL of 0.1 M NaOH is used to completely react with 4 mL of HCl. Calculate the molarity of HCl and NaOH. Given: HCl volume = 25 mL NaOH = 67.05 mL moles of NaOH = 0.015000 moles How many...
Why does the titration of a strong acid (HCl) and a strong base (NaOH) have two equivalence points, while the titration of a weak acid (CH_3COOH) and a strong base (NaOH) have only one? NH_3 is a weak base (K_b, = 1.8 x 10^-5 M) and so the salt...
so now that i have my Ka value and my hydronium value i was considering making an "ICE" box to find my HA value but this is my conundrum: HCl + NaOH -> H2O + NaClwith this kind of equation i am working with my Ka should be NaCl/[HCl][NaOH]. but my Ka should look like this...
Net ionic equations (NaOH; HCl; H2O) Hi, I completed a Grade 12 experiment and now I am doing some calculations about it but I am confused. Here is the question: "Write the net ionic equation for each reaction, and note the value of ΔH for each reaction. e.g. H+(aq) + OH-(...
with this kind of equation i am working with my Ka should be NaCl/[HCl][NaOH]. but my Ka should look like this: Ka = [H+][A-]/[HA]. in the equation above i don't even know where to put my calculated hydronium value. i am so lost. basically my overall question is: how do...
The concentration of HCl in each bottle was measured by titration with 0.1 N NaOH using an autotitrator (Mettler DL70 ES). Acetic acid was obtained from BDH and its assay was found to be 99.9 wt.%. Formic acid was obtained from a local service company and its assay was found to be ...

The purpose is to identify the precise amount of titrant needed to neutralize the analyte solution and reach a chemical reaction endpoint.Answer and Explanation: The equation for the reaction between NaOH and HCl is: {eq...
In chemistry laboratories many different types of chemicals are present. These chemicals are preserved in a bottle with the name of the chemical. Some common chemicals are HCl and NaOH. Answer and Explanation:1 HCl is hydrochloric acid. It is a strong acid. This acid is hazardous liquid ...
