What do you need to know about filter in order to predict which molecules can pass through?

User Avatar
You would need to know the size of the spaces in the filter to work out what will fit through.

Who was Rosalind Franklin?

User Avatar
Rosalind Franklin was a distinguished scientist whose research played a pivotal role in discovering the structure of DNA. However, she wasn’t widely credited for that discovery until fairly recently. She earned her PhD in physical chemistry from Cambridge University in 1945, and she did her pivotal DNA research at King’s College between 1951 and 1953. The controversy over her role in the discovery of DNA’s structure stems from the fact that Maurice Wilkins, another researcher at King’s College, showed Franklin’s images of DNA to James Watson, another scientist trying to create a DNA model. Watson and his research partner Francis Crick published a paper about it shortly after, and Wilkins, Watson, and Crick all went on to receive a Nobel Prize for the double helix DNA model. Franklin was not recognized. She spent the rest of her career studying viruses at Birkbeck College, and she passed away in 1958.

What is the pH of a 1 millimolar NaOH soluiton?

User Avatar
1 millimolar = 0.001 M NaOH ( a base, remember ) - log(0.001 M NaOH) = 3 14 - 3 = 11 pH ----------
