A sample of insoluble chlorides was prepared for analysis using aqueous solutions of lead (II) nitrate, silver nitrate, and mercury (I) nitrate with concentrated hydrochloric acid. To a portion of this sample, aqueous NH3 was added followed by a nitric acid solution, and a white precipitate was formed. Required:
a. What ion is present in this sample (i. e. what ion is responsible for the formation of the precipitate)?
b. What is the net ionic equation for the formation of the first precipitate of this ion (i. e. ion formed when concentrated hydrochloric acid was added to the solutions), including states of matter?

explanation:

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
