this is analytical chemistry please show solution thanks
The equivalence point is defined as moles acid = moles base. So first, let's calculate the initial moles of base we used. molpase Mpase = Volsoiution Molarity base = 0.100 (M) Volume of solution= _50.00 mL Moles of base = _5.00 mmol So, we need 5.00 mmol of acid (titrant) to be delivered to the analyte. Since we know the molarity of the acid and moles of acid, we just need to solve for the volume of acid (titrant) to be added. molacid Voladded Macid Molarity acid = . 0.200 (M) Moles of acid = _5.00 (mmol) Volume of acid needed to reach equivalence point (mL)

b) A solution was prepared by dissolving 1.5 g of Acetic acid (CH,COOH) in a 250cm solution. 50cm of this solution was allowed to react with 25cm of 0.1 NaOH solution (C-12, H-1, O-16) i) Determine the concentration of the acetic acid solution in moldm ii) iii) Write down an equation for the reaction. Calculate the number of moles of CH,COOH left unreacted and the number of moles of CH,COONA formed. iv) What name is given to the solution formed when all the NaOH has reacted? Calculate the Pp" of the solution in (iv) above (ka for CH,COOH = 1.8 x 10)
