Are spirit filled thermometers safer than mercury filled ones?

Your question has been heard loud and clear.

Yes , spirit filled thermometers are safer than mercury ones , actually they are made to be safer than the mercury.

In a spirit filled thermometer , it is precise and also there really is no risk of the stuff (usually alcohol or organic liquid) exploding if the thermometer glass breaks unlike the mercury thermometer , where if the glass breaks , there is a high risk of the mercury ball intoxicating the air and endangering lives.

Thank you

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
