Chapter 5, Problem 7Q

Why is important to predict the result of color mixing? Select all the apply if any.  A. It has application in industry, such in color quality control and color formulation  b. It helps you to understand the principles of absórbanle and transmission

A pH probe/meter uses the following equations: Ecell = L + 0.0592 log a1 = L - 0.0592 pH Where L = L1 + EAg/AgCI + Easy= constants  L1 = - 0.0592 log a2 a1  = activity of analyte  solution                    a2  = activity of internal solution  Questions: How will measured pH value  be affected vs “real” pH if the temperature of the sample is 30C when pH was measured?  How will measured pH value be affected vs “real” pH if HCl in pH electrode, became 0.15M instead of 0.1M?  How pH value will be affected vs “real” pH if the glass of the pH electrode is not fully hydrated? Please answer all questions and provide a brief explanation

will the liquid filtrate collecedt after filtering your solid product be acidic.

Sources of Error Determine the relationship between the observed/apparent value (EX) VERSUS that of the true value (ET) for the quantity being sought by writing either <, >, or = on the space provided TOPIC: Standardization of Titrant Adding insufficient amount of titrant to reach acceptable endpoint color: EX _____ ET

(b)Why auto temperature compensation is must for an online pH analyzer? What type of temperature element is being used for the same?

In a voltammetric analysis of an analyte the output plot is:     Current-potential curve     Current-time curve     Charge-time curve

Calculate the activity coefficient, γ , of Cu 2 + when the ionic strength of the solution, μ , is 0.069M by linear interpolation of the data in the table. \[ \gamma_{\mathrm{Cu}^{2}+}= \] Calculate the activity coefficient, γ , of Cu 2 + when the ionic strength of the solution, μ , is 0.069M by using the extended Debye-Hückel equation at 25 ∘ C , where the ion size is 600pm
