To “standardize” a solution means to determine its actual concentration. And in statistics, Standardization seems to refer to the subtraction of a mean then dividing by its SD. Titration Procedure Standardizing a Base. 0.2M hydrochloric acid standardization against borax. Answer Save. To determine the exact concentration of permanganate by titration against a solution containing a known concentration of a reducing agent. Solute Definition and Examples in Chemistry, The Difference Between Molality and Molarity, Molar Concentration of Ions Example Problem, Ph.D., Biomedical Sciences, University of Tennessee at Knoxville, B.A., Physics and Mathematics, Hastings College. You’ll need to interpret the coefficient differently. To “standardize” a solution means to determine its actual concentration. Surprisingly, there are very few resources online (outside of obscure lab pages) that explain exactly what standardization is (not even Wikipedia!). See the answer. Expert Answer. Click n=CV button below HCl in the output frame, enter volume of the solution used, read solution concentration. Our experts can answer your tough homework and study questions. Favorite Answer. The process of making any drug or other preparation conform to a type or standard. The reagent must be stable, pure, and preferably of high molecular weight. Time to do the darn thing and standardize. In statistics, standardization is the process of putting different variables on the same scale.This process allows you to compare scores between different types of variables. She has taught science courses at the high school, college, and graduate levels. , standardized solution ( stan'dărd sŏ-lū'shŭn, stan'dărd-īzd) A solution of known concentration, used as a measure of comparison or analysis. In this context, Standardize is a word that means “measure the concentration of”. NaOH + HCl → NaCl + H 2 O. NaOH solution should be titrated against methyl orange or phenolphthalein. Standardizing binary variables makes interpretation of binary variables vague as it cannot be increased by a standard deviation. “Rescaling” a vector means to add or subtract a constant and then multiply or divide by a constant, as you would do to change the units of measurement of the data, for example, to convert a temperature from Celsius to Fahrenheit. standardize - evaluate by comparing with a standard standardise appraise , assess , evaluate , valuate , value , measure - evaluate or estimate the nature, quality, ability, extent, or significance of; "I will have the family jewels appraised by a professional"; "access all the factors when taking a risk" However, without standardizing processes you make, anything you document will do more harm than good. This procedure is an easy and convenient one, especially taking into account fact, that hydrochloric acid solutions are very stable. Usually it refers to a process by which one determines the concentration of a reagent by reacting it with a known quantity of another chemical. 1 Answer. To determine the exact concentration of permanganate by titration against a solution containing a known concentration of a … Typically, to standardize variables, you calculate the mean and standard deviation for a variable. i dont know what it means to standardize a solution. What is a primary and secondary standard? Relevance. All other trademarks and copyrights are the property of their respective owners. See more. Then, for each observed value of the variable, you subtract the mean and divide by the standard deviation. A z-score, or standard score, is used for standardizing scores on the same scale by dividing a score's … © copyright 2003-2020 Study.com. The so-called titer determination or standardization of a volumetric solution used for titration is one of the most important preconditions for reliable and transparent titration results. Standardization or standardisation is the process of implementing and developing technical standards based on the consensus of different parties that include firms, users, interest groups, standards organizations and governments. 3. You standardize it by titrating it with another standardized base. A solution whose concentration is accurately known is called a standard solution. Medical Dictionary for the Health Professions and Nursing © Farlex 2012. If you were to standardise a solution, does that mean you titrate it to determine its concentration? Standard solution concentration is usually expressed in terms of molarity (M) or moles per liter (mol/L). No default solution and the decision could be difficult to make. Similarly, a solution of known concentration has been standardized. Borax has relatively high equivalent mass, which means potential errors in the standardization are smaller than … Favorite Answer. The term, stantardization means it is the only way to det view the full answer. standardize this solution using Sodium thiosulphate as a primary standard. out the proper amount to use to make a solution of any given concentration, and as the solution sits, some HCl may escape as gas. It is so you know the "active" concentration. How to use standardize in a sentence. Accurate and reliable titration results are only achievable when we work with the exact concentration of the volumetric solution. what does standardize a solution means? To check the concentration of NaOH, a chemist must titrate a primary standard—in this case, a solution of potassium hydrogen phthalate (KHP). To prepare a standard solution, a known mass of solute is dissolved and the solution is diluted to a precise volume. 2. To prepare a standard solution, a known mass of solute is dissolved and the solution is diluted to a precise volume. Standardize Binary (Dummy) Variables. What you want to do is standardize both variables (subtract the mean and divide by the standard deviation), and then add them together. 1 decade ago. What does it mean to standardize the naoh solution why can the molarity of the naoh solution not be determined accurately? So, to prevent this problem, transforming features to comparable scales using standardization is the solution. Standardized solution synonyms, Standardized solution pronunciation, Standardized solution translation, English dictionary definition of Standardized solution. 1. the condition in which a standard has been successfully established 2. the imposition of standards or regulations 3. the act of checking or adjusting (by comparison with a standard) the accuracy of a measuring instrument Familiarity information: … 2 See answers Dejanras Dejanras A standard solution is a solution (in this case sodium hydroxide) whose concentration (molarity) is known very precisely.
