# Something nullified before Pesach according to Sephardim remains permitted on Pesach. According to Ashkenazim if it was liquid ingredients it remains nullified but if it was a mixture of dry ingredients the nullification is undone when Pesach begins.<ref>Sh"t Ran 59 and Raavad in Tamim Deyim 36 write that chametz is nullified before Pesach and remained nullified. Their proof that something permitted can be nullified and stay nullified is the Mishna Kelayim 9:1. Rabbi Akiva Eiger 1:38 and Pri Chadash 447 asks that it isn't a proof is kilayim is always a prohibition as opposed to chametz. Chida 447 quotes someone who answers that on erev pesach it becomes nullified. However, Yalkut Yosef Moadim sh"t siman 2 and Yabia Omer O.C. 2:23 write that perhaps the opinion of the Rambam is that there's chozer vneer with chametz on Pesach since he holds chametz on erev pesach isn't nullified.</ref> | # Something nullified before Pesach according to Sephardim remains permitted on Pesach.

# If one piece of solid Chametz was mixed into two mixed of solid non-Chametz, such as if one Chametz cookie was mixed with two kosher lpesach cookies, one may not eat or benefit from any of the pieces.<ref>The Shulchan Aruch OC 447:9 quotes a dispute whether we say that for solid items there is nullification for chametz. The primary opinion is strict.</ref> | |||
# If a piece of food absorbed a taste of chametz even if that piece has sixty times that amount of chametz it absorbed it is forbidden to eat. If that piece was mixed with two other pieces of non-Chametz food some poskim hold that all of the pieces are permitted since the piece that absorbed chametz is nullified. However, other poskim are strict that there's never nullification even though there is a minuscule absorption of chametz in one of the pieces.<ref>The Levush YD 92 writes that if a piece of food absorbed a taste of chametz and was mixed with non-chametz foods it is nullified one in two. However, the Taz YD 92:16 argues that since there's no nullification of solid items with chametz (Shulchan Aruch 447:9) the same is true with pieces that absorb the taste of chametz. Nekudat Hakesef answers that Shulchan Aruch was only strict not to have nullification if the piece of chametz was real chametz but not if it just absorbed a taste of chametz that would have been nullified if not for the fact that it is chametz. Mishna Brurah 447:93 cites this dispute and seems to conclude that we're strict.</ref> If that piece absorbed a taste of chametz more than one in sixty then it is forbidden and forbids a mixture of two kosher pieces.<ref>Mishna Brurah 451:111</ref> | |||
# Chametz on the Erev Pesach if it is a solid mixture it is nullified one in two ad if it is a liquid mixture it is nullified one in sixty.<ref>Shulchan Aruch 447:2, Mishna Brurah 447:93. However, Shach YD 92 in Nekudat Hakesef argues that chametz on Erev Pesach isn't nullified at all since it is a dvar sheyesh lo matirin like the Rambam.</ref> | |||
