Sulphuric acid is diluted by mixing concentrated acid with water in the ratio acid :water=2 :25.It is then further diluted by adding water so that the ratio weak acid :water=1 :4.How much concentrated acid is needed to make 300mL of the final mixture.以上求高人翻译. 扫码下载作业帮拍照...
This acid is also known as sulphur dioxide solution, dihydrogen thiosulfate, or trioxosulphuric acid, depending on the source. It serves as a precursor to sulphur dioxide, which in turn produces acid rain (SO2). Trioxosulfuric acid is a colourless, odourless liquid that emits a noxious sulphur...

What happens when concentrated sulphuric acid is added to hydrated copper (II) crystals? Is copper (II) nitrate an acid or a base? What is the net ionic equation and the ionic equation for HCLO4(aq)+Mg(OH2(s)? Bases produce which ions in aqueous solution?
100 mL of a 0.1 M solution of NaOH is neutralized to pH 7 with H2SO4. How many grams of H2SO4 are required to achieve this neutralization? Neutralization Reactions Neutralization reactions are chemical reactions where an acid ...

Meanwhile, it is the residents near the mines that must pay the tax on their environment and health. Occasionally the sulphuric acid used in the mines seeps into the ground water, turning their tap water blue and sending hundreds into the hospitals. Residents complain of respiratory infections fr...
Ultra pure water (resistivity of 18 MΩ cm) produced by a Milli-Q Millipore System and suprapur sulphuric acid (Merck) were used to prepare the electrolytic solutions. The glassy carbon substrate was purchased from Carbone Lorraine. XRD measurements The crystallographic structure of the catalytic ...
This PCL-modified CNC was further used as nanofiller to prepare the PCL-CNC composite via the solution mixing process. In the presence of the modified CNC, the nanocomposite exhibited a higher modulus and ductility compared to the unmodified CNC-based nanocomposite. A similar approach was reported...
