What is the concentration of OH in a solution of 0.5M HCl? Define molar concentration What would be the concentration of a solution made by adding 250.0 mL of water to 45.0 mL of a 4.2 M KOH solution? What is the concentration of OH- ions in 0.125M Ba(OH)2 solution?
The inhibition performance of domperidone on the corrosion of copper in different concentration of HCl solution has been investigated by electrochemical, weight loss, and surface analysis, and theoretical calculation methods. Results indicate that domperidone was found to be an effective inhibitor with ...
The concentration of the solution is expressed in terms of the gram equivalent of the solute contained in the 1 liter solution. It is called an equivalent concentration expressed in symbolic N. For example, 1 liters of concentrated hydrochloric acid containing 12 grams of hydrochloric acid (HCl)...
It is a measure of acidity or basicity of the solution and as a measure of molar concentration of hydrogen ions in the solution. Answer and Explanation: Concentration of HCl = 0.400 M pH=−log[H+] pH=−log[0.4] p...
It was tested solely for its corrosion inhibition ability in a high concentration of HCl solution. The weight losses of mild steel in 6.0 mol/l HCl Conclusions Based on the experimental data and the related analyses, the following conclusions were drawn: Acknowledgement We are grateful to the ...
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 ...
原题:300 ml of 8 M Hydrochloric acid is placed in a beaker.The chemist determines that this concentration is too great for the experiment and decides to dilute this acid solution with 1,200 ml of water.What is the final concentration of the hydrochloric acid now?(Recall:M1V1=M2V2) 经过...
