What is the difference between titration and standardization?
Titration is a method used to determine the concentration of a substance in a solution by reacting it with a known concentration of another substance. Standardization, on the other hand, is the process of determining the exact concentration of a solution or reagent by titrating it against a primary standard. So, while titration is the general method for concentration determination, standardization is a specific process within titration used to calibrate solutions or reagents.
In the h2co3 - hco3 buffering system the pka 6.10 as the normal pH of blood is 7.4 is there more h2co3 or na hco3?
In blood at pH 7.4, there is more bicarbonate (HCO3-) because the pKa of carbonic acid (H2CO3) is lower than the blood pH, favoring the dissociation of H2CO3 into HCO3-. The bicarbonate acts as a buffer to help maintain blood pH within a normal range.
A 25.00 mL sample of HBr is titrated with 0.150 M standardized sodium hydoxide solution the endpoint was reached when 18.80 mL of titrant had been added calculate the molar concentration of the HBr?
Using the balanced chemical equation for the reaction between HBr and NaOH (1:1 ratio), we can determine the moles of NaOH used. From the volume of NaOH used, we can then calculate the moles of HBr present in the sample. Finally, dividing moles of HBr by the initial volume of the sample (in liters) gives the molar concentration of HBr.
What is the concetration of 400 ml of 0.5 M HCl?
The concentration of a solution is given by the formula: concentration = moles of solute / volume of solution in liters. However, to determine the concentration in this case, we need to know the moles of HCl in the solution. Given that the concentration is 0.5 M, it means there are 0.5 moles of HCl in every liter of solution. To find out how many moles are in 400 ml (0.4 L) of 0.5 M HCl solution, we use the formula: moles = concentration x volume. moles = 0.5 M x 0.4 L = 0.2 moles. Therefore, the concentration of 400 ml of 0.5 M HCl solution is 0.5 M.
Does sulfuric acid damage skin?
Acid, like any other toxin, is harmful in proportion to it's dosage -- concetration and quantity. However, HCL is most frequently used in a high concentration, and is extremely corrosive when it comes into contact with human skin. Even a gram would cause significant chemical burn damage. Be careful.
