A student following the procedure in this experiment prepared a solution by allowing 16.00 mL of a 0.250 M aqueous solution of NaOH to react with 50.00 mL of a 0.200 M aqueous solution of a weak acid, HA. The student diluted the resulting solution to a volume of 100.0 mL with distilled water. The student then used a pH meter to determine the pH of the solution and found it to be 3.910. 1.) What is the[ H;O* ] for this solution? [H;O* ] = 2.) How many moles of the weak acid were initially added to the solution? Moles HA = 3.) How many moles of OH were initially added to the solution? Moles OH- = 4.) Complete and balance the equation for the neutralization reaction in this problem: НА (аq) + NaОН (аq) 5.) Determine the number of moles of HA and A¯ at equilibrium. Moles HA = Moles A = 6.) Determine the molar concentrations of HA and A¯ at equilibrium. [ HA ] =, [A¯] =, 7.) Calculate the value of K, for the dissociation of HA K, = HA (aq) + H2O (1) = A¯ (aq) + H;O* (aq)
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.
