So far so good. The only thing I was confused on was that I was able to edit a document before actually registering. Then, finding out later, I could not even print the document without registering. I am not complaining, I was just confused. I am a senior !!

Totally worth the money! You can upload pdf's that aren't fillable and make them fillable. There are also tens of thousands of pdf documents available for downloading - not just forms, but also sample motions and briefs actually filed in court. So it's also a great tool for research.

This is a very convenient service, I loved that I could prepare my documents and save them to come back for any necessary changes. Also, how nice it is to get all the forms I need in one spot without having to search around on different websites. Thumbs up from me:)

I was looking for a free, easy to use program to complete documents because I have trouble with arthritis in both hands making it difficult and painful to hand/write. PDFfiller fit the bill to a T! I have already recommended it to my best friend who has job applications to complete. I highly recommend this online website for all your application/document needs.

I had some slight issues on my 1st attempt as there were fields in different locations than a previous edition of this form, but easily was able to correct the overwriting of several fields. Worked beautifully on several previous (new) documents.

This little program is life-changing.
This little program is life-changing. Needing to continuously reproduce docs from old paperwork and (business) historical documents is insanely time consuming. Retyping, reformatting you name it. Sometimes OCR software doesn't cut it. With this program, I've cut my frustration time by 90%. My production time is a breeze. The remaining 10% is my learning curve, but I"m figuring out more as I go, and when stuck? Kara is in chat to figure it and me out. Done.
Well worth the subscription. Thank you!

used a handful of other pdf programs, and while there have been a decent one here or there, most have been quite irresponsible, irresponsive, and irritable! pdfFiller is by far the most user-friendly, quick, and manageable one there is, notes this observer! am definitely glad i went for the platinum membership - has not only calmed my disdain towards pdfs, but i am actually having fun with them now! ^_^

easy to use but i don't use so much
its really a good app, but at the same time it does not fix all my needs, but i usually do need the app when i have to edit some pdf file, because i feel its easy to use, very intuitive, but i don't use so much
the signature features should be improved

What does it mean to standardize a solution?
Standardization is the process of determining the exact concentration (molarity) of a solution. Titration is one type of analytical procedure often used in standardization. In a titration, an exact volume of one substance is reacted with a known amount of another substance.
How do you standardize NaOH?
To standardize NaOH, start by pipetting 10.0 ml of 0.1 N hydrochloric acid (HC1) into a flask. Add approximately 50 ml of water (remember, not tap water) and three drops of methyl red indicator. Fill a 25 ml burnt with the 0.1 N sodium hydroxide solution and record the initial volume.
Why do we have to standardize the NaOH solution?
First, solid NaOH absorbs water from the air, so accurately weighing a sample during the preparation of a solution is impossible. Once the NaOH solution has been standardized and its concentration is well-known, it can be used to titrate other acid solutions such as HCl.
How do you standardize HCl solution?
Standardizing HCl(a) Pipette 25.00mL of HCl(a) into a 125mL Erlenmeyer flask and add two drops of phenolphthalein indicator. Titrate this solution with NaOH(a) to the endpoint. Calculate the concentration of the HCl(a) stock.
What do you mean by standardization?
Standardization is the process of developing, promoting and possibly mandating standards-based and compatible technologies and processes within a given industry. Standards for technologies can mandate the quality and consistency of technologies and ensure their compatibility, interoperability and safety.
What is standardization with example?
From a business standpoint, standardization refers to the practice of maintaining some level of consistency in the product or service that a company provides. A company wants to produce a consistent product, so consumers will know what they're buying. Say, for instance, a bakery produces loaves of wheat bread.
What is the purpose of standardization?
Standardization is the process of determining the exact concentration (molarity) of a solution. Titration is one type of analytical procedure often used in standardization. In a titration, an exact volume of one substance is reacted with a known amount of another substance.
What is standardization in research?
Standardization refers to methods used in gathering and treating subjects for a specific study. In order to compare the results of one group to the results of a second group, we must assure that each group receives the same opportunities to succeed. Standardization of the research methods is often a lengthy process.
