What is the most concentrated HCl?

When you substitute 1.014 mol HCl and 0.084 L into the molarity equation, we find that the molarity is around 12.07 M HCl, which is the highest concentration of HCl that we can obtain at room temperature.

What are the concentration of hydrochloric acid?

Hydrochloric acid (HCl) is supplied commercially at concentrations mainly within the range 28–36\% w/w. At these concentrations it evolves hydrogen chloride vapour with a sharp irritant odour.

Which is more concentrated 1m NaOH or 1m NaOH?

A 1 mol/kg NaOH(aq) solution contains 40 g NaOH in 1000 g water. A 1 mol/L NaOH(aq) solution contains 40 g NaOH in 1000 mL water. Thus, both solutions have effectively the same concentration.

What will happen if we added HCl instead of NaOH?

H+ + OH- → H2O. Positive sodium ions from NaOH and negative chloride ions from HCL combine to form the salt sodium chloride (NaCl), commonly called table salt.

Why is HCl concentrated?

The maximum concentration of HCl in the (commercially available) hydrochloric acid is chiefly limited by the relatively high vapour pressure of HCl over its aqueous solution, and by inherent safety considerations, such as the normal boiling temperature of the acid.

Which is more concentrated 1M HCl or 1M HCl?

For molality, one mole of HCl is added to one kilogram of water. One a very small level, the 1M HCl solution will be slightly more concentrated.

What is concentrated acid?

A concentrated acid is one in which many acid molecules are dissolved in a set volume of solution, while a dilute acid will have very few molecules per unit volume. The same applies for bases as acids. By adding water to a concentrated acid or base, the solution is diluted.

When NaOH and HCl are mixed in equal quantities the result is?

When equal volumes of hydrochloric acid (strong acid) and sodium hydroxide (strong base) solution of same concentration are mixed, the result is salt and water. This is a neutralisation reaction.

Which NaOH solution is the most concentrated?

Answer and Explanation: A 10\% NaOH solution is 2.5 M and is therefore more concentrated than a 1 M NaOH solution.

Which is more concentrated NaOH or 1 M HCl?

The 1 M solution is more concentrated than is the 0.1 M solution in NaOH by a factor of 10. At the same time there may be slightly less water in the 1 M so the 0.1 M solution might be slightly more concentrated in terms of the water concentration. How much 0.1 M HCl would you need in a 20 ml of 0.02 M NaOH to reach pH 7?

What is the reaction between NaOH and HCl with pH?

So pH of NaOH is higher than 7 and with addition of HCl, pH decreases of the solution. As mentioned earlier, due to 1:1 stoichiometry ratio between NaOH and HCl, they react in same amount. pH variation of NaOH with concentration We take three flasks which have three different concentrations of NaOH.

What is the formula for heat capacity of NaOH and HCl?

HCl (aq) + NaOH (aq) → NaCl (aq) + H2O (l) + heat. Since theses are dilute solutions and are mostly water, assume that the densities of the solutions and the specific heat capacities of the solutions are approximately 1.0 g/ml and 4.18 J/g°C, respectively.

How to neutralize HCl solution with unknown concentration?

Think you have a HCl bottle with unknown concentration. You can measure the volume of HCl solution. Also, there is a NaOH solution with known concentration. Adding this NaOH solution to HCl bottle will neutralize HCl solution. You have to choose correct indicator for this experiement.
