Question 5 1 pts A student mixes HCl and NaCl (source of conjugate) and claims to have made a buffer. Is this claim accurate? Yes- it is a mixture of acid and conjugate base after all Yes- any acid with a conjugate can make a buffer Oo oo C No-the conjugate base is so weak it does not reach equilibrium with water Need more information Question 6 1 pts Which combination of acid and base would create a buffer? Assume...
