DOI Mathematical creative thinking ability in problem solving becomes the requirement of mathematics education recently in order to find many ideas and new solution so that the issues can be resolved appropriately. This study used a mixed method design with concurrent embedded design by conducting quasi experimental design on quantitative method and Miles-Hubberman model to analyzed qualitative data. The first stage was quantitative data collection, and it was done using tests essay. The next stage was qualitative data collection, and it was done using triangulation techniques such as tests and interviews.

From the quantity of titrant required, the quantity of analyte that was present can be calculated. Determine concentration by dissolving an accurately weighed amount in a suitable solvent of known volume. High purity Stability toward air 3. Absence of hydrate water 4. Available at moderate cost 5. Soluble 6. Large F. Secondary standard: compound that does not have a high purity Determine concentration by standardisation. Titrate standard using another standard.

An estimate of the equivalence point that is observed by some physical change associated with conditions of the equivalence point.

Aim to get the difference between the equivalence point and the end point as small as possible. Respond to certain properties of the solution that change in a characteristic way.

Add excess titrant and then determine the excess amount by back titration with a second titrant. Example: The end point was reached using bromocresol green as indicator after 20 ml Ba OH 2 was added. What is the concentration of the HCl? Example: A 0. Calculate the mg CO per liter of sample. Learn more about Scribd Membership Home. Much more than documents.

Dalam kimia analitik , suatu larutan standar atau larutan baku adalah suatu larutan yang mengandung konsentrasi yang diketahui secara tepat dari unsur atau zat. Larutan standar biasanya berfungsi sebagai titran sehingga ditempatkan buret, yang sekaligus berfungsi sebagai alat ukur volume larutan baku. Larutan yang akan ditentukan konsentrasinya atau kadarnya, diukur volumenya dengan menggunakan pipet volumetri dan ditempatkan di erlenmeyer larutan standar yang digunakan untuk menentukan konsentrasi zat lain, seperti larutan dalam titrasi. Suatu standar sederhana diperoleh melalui pelarutan unsur tunggal atau suatu zat dalam pelarut yang mampu yang mana akan bereaksi dengannya. Larutan baku primer merupakan larutan yang mengandung zat padat murni yang konsentrasi larutannya diketahui secara tepat melalui metode gravimetri perhitungan massa , dapat digunakan untuk menetapkan konsentrasi larutan lain yang belum diketahui. Nilai konsentrasi dihitung melalui perumusan sederhana, setelah dilakukan penimbangan teliti dari zat pereaksi tersebut dan dilarutkan dalam volume tertentu.
