Which HCl solution has more H +? Diluted or concentrated?
Answer : Concentrated HCl means it contains more HCl whereas dilute HCl contains less acid and more water. Hence, concentrated HCl is more acidic than dilute HCl.
Why is the concentration of H2SO4 a strong acid equals the concentration of hydrogen ion *?
Strong acids with one ionizable hydrogen are completely ionized in aqueous solution; therefore, the hydrogen ion concentration of these solutions is equal to the molar concentration of the acid. Example: Hydrochloric acid is a strong acid that is completely ionized in water.
Which is stronger H2SO4 or HCl?
Generally, both Hydrochloric acid (HCl) and Sulfuric acid (H2SO4) are really strong acids compared to any other acids. However, HCl is stronger than H2SO4. This is mainly due to the difference in the basicity of both acids. Additionally, if we look at the pKa value HCl has a pKa of -6.3 and sulfuric acid has a pKa ~-3.
What is the hydrogen ion concentration of HCl?
The hydrogen ion concentration of one molar hydrochloric acid, pure water and one molar sodium hydroxide are 1, 10−7 and 10−14 mol dm−3 respectively.
What is the difference between dilute HCl & concentrate HCl?
Answer: A concentrated acid is an acid which is in either pure form or has a high concentration. A dilute acid is that in which the concentration of the water mixed in the acid is higher than the concentration of the acid itself.
Which of the solution among the concentrated HCl and dilute HCl possess the higher value of pH?
Dilute HCl has higher pH value than concentrated HCl because it has less number of H+ ions. If an acid in one of its solutions has higher pH value, then it means that the acid is in diluted form.
Why is H2SO4 a strong acid?
Sulphuric acid is a strong acid because H2SO4 completely dissociates to H+ and SO42- when it is dissolved in water to form an aqueous solution. It is also diprotic, meaning that there are 2 moles of H+ ions produced for every mol of H2SO4 that dissociates.
Can a strong acid be dilute?
An aqueous solution of strong acid can be diluted by adding more water to the solution.
What is the mixture of concentrated HCl and H2SO4 called?
Mixing HCl and H2SO4 is a deadly mistake. The mixture is known as Aqua Regia, because it can even dissolve pure GOLD metal that is one of the most chemically inert substances known to man.
What is the concentration of the HCl solution?
Hydrochloric acid is produced in solutions up to 38\% HCl (concentrated grade). Higher concentrations up to just over 40\% are chemically possible, but the evaporation rate is then so high that storage and handling require extra precautions, such as pressurization and cooling.
Which of the samples has the highest amount of hydrogen ion concentration?
Textbook solution ∴The sample which has the highest amount of hydrogen ion concentration is B since the pH for sample B is least from the rest of the samples therefore the Highest amount of hydrogen ion concentration will be in B. The decreasing order of the four samples according to their pH is C, A, D, B.
Which has higher H3O* concentration (HCl or H2SO4)?
On the basis of the commercially available acid and comparable molarity, H2SO4 has either a lot higher concentration of H3O+ or a little higher concentration, compared with HCl. When compared on the basis of the two other Which has higher H3O* concentration (HCl or H2SO4)?
What is the difference between concentrated solution and dilute solution?
A concentrated solution is one that has a relatively large amount of dissolved solute. A dilute solution is one that has a relatively small amount of dissolved solute. What is the difference between a concentrated acid and diluted acid? A concentrated acid has a relatively large amount of solute dissolved in the solvent.
What is the ratio of sulphuric acid to hydrogen in electrolysis?
The electrolyte is dilute sulphuric acid (= acidified water) which, during electrolysis is split into hydrogen and oxygen gases. Theoretically into a 2 : 1 ratio by gas volume.
What is the difference between hydrochloric acid and sulfate?
1. The electrolysis of many salts (e.g. sulfates of reactive metals) or sulfuric acid produces hydrogen at the negative cathode electrode and oxygen at the positive anode electrode. Whereas hydrochloric acid gives chlorine at the anode (as will all chloride salts), the sulfate ion does nothing and instead oxygen is formed.
