Question

1. How many moles of a 0.1 M HCl are in your analyte if you use 20 mL and how many moles of NaOH are needed to neutralize it?  Explain what these terms mean in chemistry : burette, titration, solution, solute, solvent, indicator, and standard solution.

Answer 1

Molarity of HCL (m_1) = 0.1M volumes of HCL = 20 mL = 0.020L therefore no of molar of HCL = M_1 V_1 = 0.1 times 0.020 Hcl + NaOh rightarrow Nacl + H_2o as this 1: 1 rx_n same No of moles of NaOH are needed therefore moles of NaOH needed = 0.0020 burette It is an apart us used in volumetric analysis the solution which is taken in Burette is called titan. Generally its capacity is 50 mL. microburnetts are also available. Titration: - The process of adding a solution from Burette to another solution taken in conical flask in order to known the end point is called as titration. - It is a homogeneous mixture of two or more components. if the solution consists of two subtraction it is called as binary solution. solute: The substance which is relatively present in small in solution consist of two substrate it is called solute eg: - Glucose is solution
