9.You need 100 mL of a 0.1 mol/L hydrochloric acid, HCl, and all you have in stock is a bottle labeled 12.0 M HCl. How can you prepare the solution you need?10.If 0.75 L of a 5.00 M solution of HCl is diluted to a volume of 1.80 L by adding water, what is the ...
The concentration of HCl(aq) was 2M (ie, I think, 73g of HCl per 1 litre of water?). I'm curious to know - what concentration of HCl would be harmful on the skin? Can anyone tell me please? Thanks.
For example, 1 liters of concentrated hydrochloric acid containing 12 grams of hydrochloric acid (HCl), then the concentration of 12.0N. Equivalent concentration = solute gram equivalent / solution volume (L) 3, mass volume concentration The concentration represented by the mass quantity of solute ...
However, the observation of surface cracking in modified E-glass having 5% Na2O or K2O upon immersion in HCl (pH = 2) suggest [3] that the diffusing species in acidic media are H+ and not H3O+ as in the reaction with water. The suggested reaction is similar to Eq. (17.1): (17.6)...

For moderately concentrated solutions of 1,1 electrolytes this time is in the nanosecond range. At longer times cations and anions diffuse with a common diffusion coefficient and the ionic equations can be replaced by component equations. The general method for solving Eqs. (11) consists of transf...
A process for regenerating waste acid, such as waste hydrochloric acid pickling liquor by producing aqueous hydrochloric acid of pickling concentration and generating iron oxide including that of pigment grade, comprises the steps of (1) concentrating the waste liquor, (2) reacting the concentrated ...
