Webb50 mL of 0.05 M Na 2CO 3 is titrated against 0.1 M HCl. On adding 40 mL of HCl, pH of the solution will be [Given for H 2CO 3, pK a 1=6.35; pK a 2=10.33; log3=0.477, log2=0.30] A 6.35 B 6.526 C 8.34 D 6.173 Hard Solution Verified by Toppr Correct option is D) The number of milliequivalents of sodium carbonate =50×0.05=2.5 WebbAll right, so the concentration of HCl in our original solution would be, we had 0.000844 moles. All right, divide that by liters. That was 0.0200 liters, right? 20 milliliters is equal to 0.0200 liters. And so we can do our calculation here. So we can take 0.000844, and we can divide that by 0.0200, and we get for our answer here 0.0422 molar.

If you're titrating hydrochloric acid with sodium hydroxide, the equation is: HCl + NaOH → NaCl + H 2 O. You can see from the equation there is a 1:1 molar ratio between HCl and NaOH. If you know that titrating 50.00 ml of an HCl solution requires 25.00 ml of 1.00 M NaOH, you can calculate the concentration of ...
WebbThe pH of ~0.002 mol of H3O+ ions = 1.698 (rough rounding, but lower pH value...) Is it correct to say then that because the incremental H3O+ mols are so negligent, we overlook these moles as well as the (ever smaller) products from continued reactions that will lead to additional H3O+ moles? Webbinitial pH, before the addition of strong base. In dealing with strong acids and bases, assume that they dissociate completely in water. [H+] = [HCl] In this example, we have a 0.1 M solution of HCl, so the [H+] = 0.1 M - log (0.1) = …
Webbför 2 dagar sedan · On the reaction of HCl with water, HCl completely breaks down to release hydronium and chloride ions. Cl- is the conjugate base. A strong acid leads to the formation of a weak conjugate base. It is believed that the weaker the conjugate base is, the stronger is the acid. For strong acids, the value of pKa is less than -1.74. For HCl, pKa …
WebbWhat is the pH of 0.1m of CA (OH) 2? You assume the ionic dissociation constant, K, of water. K = [H+] x [OH-] = 10^-14 at 20 C.

Smaller values of \(pK_a\) correspond to larger acid ionization constants and hence stronger acids. Conversely, smaller values of \(pK_b\) correspond to larger base ionization constants and hence stronger bases.
