Nzọụkwụ 4: Tinye Ammonium Hydroxide

Jiri nwayọ tinye ammonium hydroxide na ngwọta citric acid mgbe ị na-akpali.Mmeghachi omume n'etiti citric acid na ammonium hydroxide ga-emepụta ammonium citrate na mmiri dị ka ndị a:3NH4;OH+C6;H8;O7;→(NH4;)3;C6;H5;O7;+3H2;O

Nzọụkwụ 5: Nyochaa pH

Ọ bụrụ na ị nwere mita pH, nyochaa pH nke ngwọta ka ị na-agbakwunye ammonium hydroxide.pH kwesịrị ibili ka mmeghachi omume na-aga n'ihu.Ebumnuche maka pH gburugburu 7 ruo 8 iji hụ na mmeghachi omume zuru oke.

Nzọụkwụ 6: Gaa n'ihu na-akpali akpali

Nọgide na-akpali ngwakọta ahụ ruo mgbe citric acid emeghachila nke ọma na ngwọta ya doro anya.Nke a na-egosi na e mepụtala ammonium citrate.

Nzọụkwụ 7: jụrụ na crystallization (Nhọrọ)

Ọ bụrụ na ịchọrọ inweta ụdị kristal nke ammonium citrate, kwe ka ngwọta ahụ dị jụụ nwayọọ nwayọọ.Crystal nwere ike ịmalite ịmalite ka ihe ngwọta na-ajụ oyi.

Nzọụkwụ 8: Nzacha na ihicha

Ozugbo mmeghachi omume ahụ zuru ezu na ngwọta doro anya (ma ọ bụ crystallized), ị nwere ike nyochaa ihe ọ bụla na-agbazeghị.Mmiri fọdụrụnụ ma ọ bụ kristal siri ike bụ ammonium citrate.

Nzọụkwụ 9: Nchekwa

Chekwaa citrate ammonium n'ime akpa ikuku, pụọ na ọkụ na ọkụ ka ọ kwụsie ike.
