Which of the following actions will increase the solubility of agbr in water? a) increasing the ph b) decreasing the ph c) adding nabr d) adding nano³ e) none of the above.

Answer;

e) none of the above.

Explanation;Solubility is the maximum quantity of solute that can dissolve in a certain quantity of solvent or quantity of solution at a specified temperature or pressure.Solubility depends on factors such as temperature, pressure, molecular size, polarity and a factor such as stirring which increases the speed of dissolving.Therefore; factors such as pH or adding another compound, do not affect the solubility of a substance such as AgBr.

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
