The method for mixing sulphuric acid with water is carried out by supply of acid and water into a common vessel, which is sulphuric acid absorber. Acid into the absorber will be given with the concentration, which is less than 98.3 %, through the distributing plates of absorber to the ...
The acid can be sulfuric acid or a mineral acid. The gas which forms an acid upon contact with water can be carbon dioxide, sulfur dioxide, or other acidic forming gases. As used herein the phrase “long chain carboxylated carbohydrate” refers to carboxylated carbohydrates having average molecul...
A mesoporous carbon is prepared by mixing a carbon precursor, an acid, and a solvent to obtain a carbon precursor mixture; impregnating an ordered mesoporous silica (OMS) with the carbon precursor mixture; carbonizing the impregnated OMS at 800 to 1300掳 C. by irradiating microwave energy with...
Step-by-Step Solution:1. Understanding the Reaction: When mixing sulfuric acid (H₂SO₄) with water, it is important to recognize that this is a dilution process. H₂SO₄ is a strong acid, and when it i
The heat of mixing data for the sulfuric acid (1) and water (2) mixture at 294 K is represented by Ross (1952) as ΔH∼mix(kJ/mol)=x1x2-53.531+20.869(x1-x2). The pure component enthalpies for sulfuric acid and water are 1.596 and 1.591 kJ/mol, respectively.Solution...

of the resist pattern off the substrate with the mixed solution, the pure water tends to bring about a dissolving reaction with the sulfuric acid remaining on the substrate. What should be noted is that the dissolving reaction brings about the mist generation and scattering of the sulfuric acid...
