The pH of the substance is 3.3 which is acidic.
<h3>What is pH?</h3>
The pH of a substance or solution is referred to the degree of acidity or alkalinity of that substance. It is measured on a scale of 0 -14.
Given the concentration of hydrogen ions as 5. 0 × 10–4 moles per liter,we use the formulae
ph = –log[h+]
plugging in thge value of h+ as 5. 0 × 10–4 moles per liter we have:
pH = –log{5. 0 × 10–4 ]
pH=3.3

The mesentery, Coffey argues, should be considered an organ because it holds up our intestines (a discrete role) and has a distinct structure. “It has a beginning and an end, and in between it kind of fans out like a Chinese fan,” he says, and is usually about two feet long
The 1960s was marked by the cold war between the two super powers of the World, Russia and the United States. These countries were often represented as Blue and Red on a map, blue signifying the United States and it's ally countries and Red signifying communist Soviet Union and it's allies around the world. If someone from the Soviet Union would look at the map, they would be nervous to see American Allies all around the world, including Western and Northern Western European countries, some of which were at a close distance to Moscow. On the other hand, if an American looked at the world map, they would see a Giant red Soviet Union covering all of Northern Asia and Eastern Europe. They would also see other communist countries including Cuba, where the Soviets even placed Nuclear weapons, targeted at the United States.
