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.
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 broth selective?
yes
What is the chemical composition for brightening row brass metal?
1]10% aquas solution of KCN OR NaCN containing ~5 gm/ litr KOH OR NaOH 2]20% aquas solution of sulphuric acid containing~5gm/litr chromic acid
Why kcn is inorganic?
because it exists as K+ and CN-
What dissolved species are present in a solution of KCN?
K+(aq),CN-(aq)
What is KCN base acid or neutral?
KCN is a neutral solid salt (poison) but its aqueous solution is slightly basic.
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.
What is the pH of KCN?
KCN is a salt of strong base weak acid. Therefore its water solution will be basic. Hence, its pH will be greater than 7. ^So what is its pH?
Why kcn bonding is through carbon and agcn bonding through nitrogen?
Because KCN is a ionic compound but AgCN is covalent compound . So, when KCN is dissolved the we get K+ ion and CN_ ion then bonding takes place through carbon but in AgCN doesn't give ions so bond formation takes place form free side of AgCN or from nitrogen.
What number of mole is KCN?
The answer will depend on the quantity of KCN.
What would cause addition of KCN to water?
Since potassium cyanide (KCN) is highly poisonous, the addition of KCN to water might be caused by an intention to kill.
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
How do you prepare kcn?
We can prepare KCN by the reaction of KOH and HCN.Where HCN can be generated by the pyrolysis of formamide.
Is KCN ionic?
Yes
