Accurately prepare a 50cm stock solution of (approx.) 0.003M potassium permanganate solutic Very Important;- Before proceeding with the preparation of this permanganate standard, discu your calculations with the demonstrator. Calculate the weight of potassium dichromate required to prepare 50cm of a 0.015M stock solution and confirm your calculation with the demonstrator. Note;- Solid potassium dichromate will not be handled or weighed by the students during this experiment but instead and as an added safety step, will be provided in solution form. Dispense from a burette 1, 2, 3, 4 & 5cm' of the permanganate solution into five separate 50cm volumetric flasks and prepare to the mark with distilled water. Calculate the Molarity of each of the 5 solutions. Repeat this procedure for the provided standard dichromate stock solution, calculating the Molar concentrations as before.
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
can someone calculate the 10 concentrations please ?
