From the equilibrium of water dissociation,
kW is equal to the product of hydrogen ions and hydroxyl ions. The hydrogen ion concentration is 1x10^(-4). Hence, at 298 K, the hydroxyl ion concentration would be 1x10^(-10).
Water equilibrium equation: Kw = [H+] * [OH-] = 1.0*10-14 (at 25oC)So [OH-] = 1.0*10-14 / 1.0 M HCl = 1.0*10-14 mol/L OH-
To make a 1% HCl solution from a 35% HCl solution, you would need to dilute the concentrated solution with water. The ratio of concentrated HCl to water would be approximately 1:34. So, to make 1% HCl, you would mix 1 part of the 35% HCl solution with 34 parts of water.
In solution with a pH of 1 [H+] is 0.1M. Since HCl is a strong acid [HCl] will also be 0.1M. So, in 1 liter of solution you will have 0.1 mol of HCl.
The normality of a solution is a measure of the concentration of a solute in a solution. For HCl (hydrochloric acid), the normality would depend on the concentration of the HCl solution. For example, a 1 M (molar) solution of HCl would be 1 N (normal).
To prepare a 0.2N HCl solution from 1.0N HCl, you can dilute the 1.0N HCl solution by adding 4 parts of water to 1 part of the 1.0N HCl solution. This means combining 1 volume of 1.0N HCl with 4 volumes of water to obtain the desired 0.2N HCl solution.

To prepare 1 M hydrochloric acid (HCl) solution, you usually need to dilute concentrated HCl solution (~35-37% HCl) with water in a specific ratio. The specific volume of concentrated HCl needed depends on its concentration and the final volume of the 1 M solution you want to make. In this case, 85 ml of concentrated HCl is likely to be the volume needed to make 1 L of 1 M HCl solution.
40 ml of NaOH contains 0.04 L * 3.5 M = 0.14 mole of NaOH Since NaOH donates 1 OH you will also have 0.14 mole of OH- in solution. This can be neutralised with an equal amount of H+. HCl can donate 1 H+, so you need an equal amount of H+ to neutralise the OH-. So you need 0.14 mole of the HCl. 55 ml has 0.14 mole HCl. So the molarity is: 0.14 mole / 0.055 L = 2.54 M
1 HCl + 1 NaOH ---> 1 NaCl + 1 H(OH)
1 N HCl (hydrochloric acid) is equivalent to a concentration of 0.1 M (molarity), which means it contains 1 mole of HCl per liter of solution. The percentage of HCl in 1 N solution is about 3.65%, calculated based on the molecular weight of HCl.
You would need to dilute the 0.1N HCl solution with distilled water in a 1:9 ratio (1 part HCl solution to 9 parts distilled water) once in order to obtain a 0.01N HCl solution.
I assume you mean molar instead of mole?Fast:The HCl solution is 3 times as concentrated.Since both can only donate 1 H+ or OH-...you wil need 3 times as much NaOH to neutralise the HCl.20 ml * 3 = 60 mlSlow:The HCl solution has 6 mol/LThere is 20 ml of it, so you have 0.02 L * 6 mol/L = 0.12 mol of HClEach mole of HCl donates 1 mole of H+So there is 0.12 mol of H+ that you have to neutralise.This equals to 0.12 mol OH-Each NaOH donates 1 OH-So you need 0.12 mol NaOHThe NaOH solution you are using has 2 mol/LSo you have to use 0.12 mol / 2 mol/L = 0.06 L = 60 ml
they both are same as HCl is a monobasic acid.>>>Not exactly. N stands for normal and M stands for mole. Knowing that, read this article to know the difference:http://answers.yahoo.com/question/index?qid=20070625100319AALNjoW
