(1) A beaker with 165 mL of an acetic acid buffer with a pH of 5.00 is sitting on a bench top. The total molarity of the acid and conjugate base in the buffer is 0.100M. A student adds 7.20mL of a 0.320M HCl solution to the
I have liquid concentrated HCl (37%w/w) To prepare 100ml of 10g/L HCl as a solvent medium, is it acceptable to just weigh 1g of liquid conc HCl and dilute to 100ml with water? What volume of conc HCl should we use to make 100ml of
0.5g of MG ribbon is reacted with 100ml of 1M HCL. The initial temperature of HCL is 20.4 degrees celsius. After the reaction the highest recorded temperature is 40.7 degrees celsius. Calculate the molar enthalpy of MG. I tried to
calculate the change in pH when 9.00ml of 0.100M HCl(aq) is added to 100.0mL of a buffer solution that is 0.100M in NH3(aq) and 0.100M NH4Cl(aq). ...Calculate the change in pH when 9.00,L if 0.100M NaOH(aq) is added to the
What volume, in ml, of a 60% of HCl acid solution must be added to 100 ml of a 30% HCl solution to make a 36% HCl solution. We need 2 alegabreic (?) equations. The first I can get is: 0.36x - 0.60y = 100ml (this is probably
