What formula do you use to determine if an acid is protonated or deprotonated when given the pH and {eq}pK_a {/eq}? Acid-Base Reactions: Acids and bases mainly react to form neutral solutions, a reaction termed neutralization reaction. protonation of ...
What is the pH of a solution containing 0.160 mol L^{-1} of HCl and 0.828 mol L^{-1} of a weak acid with pKA = 4.63 ? What is the pH of a 0.028 mol/L solution of HClO4(aq)? What is the pH of a solution containing 0.395 mol L^(-1) CH3NH2 and 0.251 mol L^(-1) CH3...
The lysates were cleared by centrifugation (12,000 × g for 30 min at 4 °C) before proceeding with purification as described in details below for the different proteins. In all cases the proteins of interest were expressed fused with a N-terminal His6SUMO-tag, which was removed ...
Since the granules are often positioned in close distances and their diameter is often below 300 nm, a high-resolution microscopy technique has to be employed to estimate their amount in the cells. We used structured illumination microscopy (SIM) followed by Amira software analysis of insulin ...
If it is true and if the number of posts to show is greater than the specified `limit`, render a link to another page. To specify the URL and the text of the link, you can set `show_more_url` and `show_more_text` attributes, which are documented below. + - `show_...
It can be measured using the conventional litmus paper method or using the more advanced pH meter. Answer and Explanation: The reaction of the Tris with the added acid is given by the equation below: {eq}\rm Tr...
is mixed with 100 mL of 0.1 M H3PO4, what is the pH of the buffer mixture? The pKa of H3PO4 is 2.1. Acidic Buffer Solution:Let us assume the addition of a small amount of acid or base to a buffer solution. The chang...
Answer to: A buffer solution is made using a weak acid, HA. If the pH of the buffer is 6 and the ratio of A^- to HA is 0.001, what is the pK_a of...
Acetic acid is a monoprotic weak acid and NaOH is a strong base. When they are mixed together, they will neutralize each other's properties and produce an alkaline salt in the resulting solution. The chemical reaction is written ...
pH = pKa + 0.70 E. pH If you were asked to place potato strips in a solution that would cause the potato to neither gain or lose mass, what molarity would you choose and why? Would this solution be hypotonic, hypertonic, or isotonic? Ordinary table salt is referred to...
