Yes, Potassium cyanide is highly soluble in water die to being a highly reactive acid.
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
yes
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.
because it exists as K+ and CN-
Cyanide is usually made using ammonia, methane, and oxygen with a platinum catalyst. 2CH4 + 2 NH3 + 3O2 --> 2HCN + 6 H2O The cyanide is in the form of hydrogen cyanide, which is liquid at room temperature, but will readily become a gas. The common solid, water-soluble forms of potassium cyanide (KCN) and sodium cyanide (NaCN) are made by reacting hydrogen cyanide with the corresponding hydroxide in water. For example: KOH + HCN --> KCN + H2O.
The answer will depend on the quantity of KCN.
Since potassium cyanide (KCN) is highly poisonous, the addition of KCN to water might be caused by an intention to kill.
KCN kills a human being in 0.5 second.
CuSO4 + KCN --->Cu(CN)2 + K2SO4
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
We can prepare KCN by the reaction of KOH and HCN.Where HCN can be generated by the pyrolysis of formamide.
Yes
KCN is a neutral solid salt (poison) but its aqueous solution is slightly basic.
Examples of poisonous salts: KCN, HgCl2, NaCN.
yes
yes
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.
