The Arrhenius definition does not explain why substances such as NaCO3, which don't have a hydroxide ion that can dissolve in water, nevertheless display properties typical of bases. The definition also works only for reactions in water because it specifies that bases have to dissolve in water. ...
What acid is found in gastric juice? What does bicarbonate of soda do to your stomach? What is GERD without esophagitis? What is erosive gastritis? What is arachidonic acid? What is the pH of an acid? What is a weak acid? What is a strong acid?
date (How Long Does Milk Last?¹). True expiration dates, when a product is deemed unsafe from that time on, aren’t used very often on food items. There are a number of factors that will determine the shelf life of milk. First, the way that a processing plant processes the milk w...
What does base strength and acid strength mean? How do you determine the strength of an acid? What is a strong acid? Explain how a strong acid is different from a concentrated acid. Which is a stronger acid? (a) HI (b) HCl.
As the word benign suggests, BPH does not indicate severe diseases like cancer or other malignancies. However, it can cause some discomfort, as we will explain below. Figure 1: Enlarged prostate. What are the symptoms of BPH? Enlarged prostate symptoms can be subtle and as a result, remain...
Of course, factors such as loving relationships, good health, the skills to earn a living and a peaceful environment all contribute to our happiness too. But this does not mean that people without these conditions cannot be happy. 38
A solution of a strong acid has a pH of 3. What is the concentration of hydronium ions in this solution? (Hint: What is the pH of a solution that has a pOH of 12? What is [OH^-] in a solution that has a pH of 4.35?
「过量」是指「超过所需」。 例如有一杯氢氧化钠溶液(Sodium hydroxide solution)，需要加入十个单位的硝酸(nitric acid) 以达至完全中和。 如果我只加入五个单位的硝酸，那硝酸不足以与全部氢氧化钠反应；硝酸是「 *** 」limited，氢氧化钠是过量(in excess)。 如果我不多不少、正好加入十个单位...
Specifically, the acidic species is a molecule or ion that donates one or more protons by dissociating the same number of "H-X" bonds. This increases the hydronium ion concentration in the solution containing this acid. A Bronsted acid may be relatively weak or stro...
Lewis acids refer to those acids that possess the ability to form a covalent bond with two electrons. Boron trifluoride is one of the examples of such acids. Titration signifies the process of detecting the acid concentration in a specific solution. ...
