KOH CONC is 0.032 Volume added is 40cm3 Propanoic acid conc is 0.024 volume added is 25cm3
kW is 1.0x10-14
Calculate the pH
By the sounds of it, it looks like a stoichiometry style question. Im guessing form an equation with the two chemicals, find the conc of water, and then use the kw equation to find OH ions and do the log of that

Sorry ignore my last answer. Okay formulate an equation find the initial number of moles and do stoichiometry to find the moles of the product. Then use n=cxv but the volume is the two volumes added together as the two chemicals have been mixed. Then you will know OH ions then find H ions from kW and do LOg for ph

Thank you! I got an answer of 13.96 is that right?
Calculate moles of Na im guessing its 1:1 ratio, then find the mass of aspring and find 78 percent of the value
