Why is colored liquid good for diffusion experiments? please answer urgently needed i will give you a heart and brainliest

Is a logical series of steps

Answerthis solution will not form a precipitateexplanationsolubility equilbrium:         pbf₂(s)  ⇄ pb²⁺(aq) + 2 f⁻(aq)the solubility product expression is    (we exclude solids from the equilibrium expression).now suppose we have the trial ion product q, which we can define as    then, we can interpret  q as the product of the concentration of the ions that we have and ksp as the product of the ion concentrations that are needed to form a saturated solution.if q > ksp, then that implies that there will be a surplus of ions that exceed the amount that is required to form a saturated solution. a precipitate will then form (the precipitate continually  forms until the surplus ions are removed and q is decreased to ksp's value).if q = ksp, the saturated solution that forms is barely saturated and the precipitate will be minimal.if q < ksp, then the ion concentration will not be enough to form a saturated solution (so no precipitate).using our information, we calculate the trial ion product:     since q = 2.7  × 10⁻⁸ < ksp =  4  ×  10⁻⁸, a precipitate will not form.

Small amounts of matter are converted intolarge amounts of energy occurs in both fusion and fission reactions. they are nuclear reactions where a change in the identity or characteristics of an atomic nucleus results when it is bombarded with an energetic particle, as in fission, fusion, or radioactive decay.

Answer is: mass of hydrochloric acid is 4,08 grams.chemical reaction: 2hcl + mg(oh)₂ → mgcl₂ + 2h₂o.m(mg(oh)₂) = 3,26 g.n(mg(oh)₂) = m(mg(oh)₂)  ÷ m(mg(oh)₂).n(mg(oh)₂) = 3,26 g  ÷ 58,32 g/mol.n(mg(oh)₂) = 0,056 mol.from chemical reaction: n(mg(oh)₂) : n(hcl) = 1 : 2.n(hcl) = 2  · 0,056 mol = 0,112 mol.m(hcl) = 0,112 mol  · 36,45 g/mol.m(hcl) = 4,08 g.
