chemical reaction more likely to occur without being permanently changed by the reaction.

@albairaqqatar tubing from the control beaker to the large beaker of water than we will record the color of the liquid in the control beaker

[Diamond @Khorg_Diamond8]

@albairaqqatar When gas has bubbled into the liquid in the control beaker for 30 sec

[Diamond @Khorg_Diamond8]

@albairaqqatar we will tip of the medicine dropper that is attached to the flexible tubing should be submerged in the liquid in the beake

[Diamond @Khorg_Diamond8]

@albairaqqatar Place the free end of the flexible tubing that extends from the glass tube containing the catalyst into the control beaker

[Diamond @Khorg_Diamond8]

@albairaqqatar Then we will add 5 drops of phenolphthalein to the water.

[Diamond @Khorg_Diamond8]

@albairaqqatar •respectively.to each beaker, add 1ooml of water

[Diamond @Khorg_Diamond8]

@albairaqqatar We will label sixe beakers control #1,#2,#3,#4,and#5, respectively.

[Diamond @Khorg_Diamond8]

@albairaqqatar the ammonia solution in the flask consists of ammonia gas dissolved in water

[Diamond @Khorg_Diamond8]

@albairaqqatar we will take 500-ml Erlenmeyer flask containing a solution of water,ammonia,and phenolphthalein

[Diamond @Khorg_Diamond8]

@albairaqqatar Obtain the metal catalyst we will use for investigation,

[Diamond @Khorg_Diamond8]

@albairaqqatar compare three metal but we will use copper turnings.

@albairaqqatar وذلك على حساب النيكوتين الممتز أصلا وفى هذه الحالة يمكن أن نستخدم غاز الأمونيا

[Diamond @Khorg_Diamond8]

@albairaqqatar الأمونيا NH3 تنتشر بسهولة بالمقارنة بأيون الأمونيوم NH4+.
