How fast KCN kills human?
KCN kills a human being in 0.5 second.
CuSO4 reacts with KCN to give what?
CuSO4 + KCN --->Cu(CN)2 + K2SO4
What is the formula for the compound that forms from potassium and cyanide?
To answer this you need a roman numeral on gold to know the charge on it. Assuming it would be (I)... the formula would be KAu(CN)2
Is KCN ionic?
Yes
What is KCN base acid or neutral?
KCN is a neutral solid salt (poison) but its aqueous solution is slightly basic.
What salt is poisonous?
Examples of poisonous salts: KCN, HgCl2, NaCN.
Is KCN broth selective?
yes
Is KCN a ionic compound?
yes
Does 0.1 M KCN have a pH greater than 7.0?
Yes. Since KCN is a salt of strong base and weak acid,its water solution will be basic.Therefore,0.1M KCN have pH greater than 7,its pH is 11.
Why is cyanide poison?
Cyanides (HCN, KCN, NaCN) are lethal poisons, which block the respiration.
