Which would be least likely to completely dissolve in water?

a. hydrochloric acid
b. sulfuric acid
c. nitric acid
d. acetic acid

The right option is; D. acetic acid

Acetic acid would be least likely to completely dissolve in water.

Acetic acid is a simple, colorless, organic acid which can be found in vinegar. Acetic acid has antibacterial and antifungal properties, and it gives the vine gar its sour taste. Acetic acid is a weak acid and because of this, it does not completely dissociate in water. The dissociated forms and those that are intact are in equilibrium in water solution. Acetic acid will dissociate in water to produce acetate ions, and hydrogen ions which will later mix with water to form hydronium ion.

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
