During reduction of 3-nitroacetophenone using Sn and HCl, why is the sodium hydroxie added after the Sn/HCl reduction is complete. Why does the pH need to be increased??

Can someone explain why Granular tin, Concentrated HCl, and NaOH are used in a reduction of m-Nitroacetophenone to 3-aminoacetephenone? Why would someone use these specific things for the reaction? What is the role of each of them?
In the experiment reduction of benzophenone with sodium borohydride, why was the solution heated to boiling after addition of sodium borohydride? why was it added to ice? THANK YOU!!!
What was the purpose of cooling your solution (of sodium benzoate and water), after adjusting the pH with HCl? ----- (why would we need to cool the solution?) does it have any effect on the precipitation??
If 5 mL of 0.1M HCl is added to 50 mL of 0.1M sodium phosphate buffer at pH 7.0, what is the resulting pH?
Why does the second drop of 0.1M HCl added to 0.1M NaCl change the PH less than the first drp of 0.1M HCl?
.01 moles of gaseous HCl is added to 100-ml of the buffer composed of .5M sodium acetate and .5M acetic acid. Find the pH
A 0.200 M solution of HCl is added to a solution containing 0.150 moles of sodium phosphate (Na3PO4). The resulting solution is then diluted to exactly 1.00 L, at which time the pH was found to be pH 8.00. What is the concentration of H2PO4- in the solution? For phosphoric acid, Ka1 = 7.11 x 10-3, Ka2 = 6.32 x 10-8, and Ka3 = 7.1 X 10-13.
a) Buffer solutions with a pH values of around 10 are prepared using sodium carbonate (Na2CO3) and sodium hydrogen carbonate (NaHCO3). What is the pH of a solution of 10.0g each of the two salts in enough water to make 0.250 L of solution? pKa2= 10.33 b) By how much does the pH change when 3.5mL of 6.0 M HCl is added? c) By how much does the pH of the solution change when 0.92 g of NaOH is added?
2. Why anhydrous sodium sulfate is added to the t-butyl chloride in the purification process? Could solid sodium hydroxide be used instead of anhydrous sodium sulfate? 3. The reaction from t-butyl alcohol and HCl gives t-butyl chloride. Is it SN1 or SN2 reaction and why?
in the reduction of benzil to hydrobenzoin using sodium borohydride, why is meso-hydrobenzoin the predominant product in this reaction ? please explain clearly and provide the mechanism
