The general equation is:
This is one of the more common acid-base reactions. This reaction is one of the few processes to make sodium chloride using hydrochloric acid and sodium hydroxide:
An acid can also react with a carbonate, which is a relatively weak base. An example is
acetic acid reacting with calcium carbonate to form calcium acetate, carbon dioxide and water:

Crow Nation
The Crow (also known as Apsáalooke in their own Siouan language, or Absaroka) are Native Americans. In the past, they lived in the Yellowstone River valley, which is in Wyoming, Montana, and North Dakota. Today, they are federally recognized as the Crow Tribe of Montana.
During their history, the Crow have changed their territory many times because of conflicts with the Ojibwe, Cree, Cheyennes, and Lakota (Sioux) peoples. They were generally friendly with the whites. Since the 19th century, most Crow people have lived on their reservation that is south of Billings, Montana. Although they have lost land, it is over 9300 km. They also live in several major western cities. The tribe's headquarters are located at Crow Agency, Montana.
The name Apsáalooke means "children of the large-beaked bird". The French translated the name as "gens du corbeaux" ("people of [the] crows"), and they became known in English as the Crow. Other tribes also refer to the Apsáalooke as "crow" or "raven" in their own languages.
In 1743 the Crow first encountered people of European descent. They were French fur traders.
The Crow and Hidatsa used to be the same tribe. They were nomadic hunters and farmers. The earliest known home of the Crow-Hidatsa tribe was in present-day Ohio. They were pushed out by stronger neighbors and moved to Manitoba. Later, they moved to North Dakota, where they split from the Hidatsa. The Crow were then pushed westward, mostly by the Cheyenne and Sioux.
To gain control of their new home in the Yellowstone River valley, they fought against the Shoshone and drove them westward. They were allied with some of the Kiowa and Kiowa Apache. The Crow were an important tribe in this area through the 18th and 19th centuries, the era of the North American fur trade.
After they started living in this area, the Crow divided into four groups: the Mountain Crow, River Crow, Kicked in the Bellies and Beaver Dries its Fur. They adopted the nomadic lifestyle of the Plains Indians, becoming gatherers and bison hunters.
Around 1740, the Plains tribes, including the Crow, started using horses. This allowed them to hunt buffalo more actively. The Crow became well-known horse breeders and dealers. Sometimes, their horses were stolen by tribes like the Blackfoot Confederacy, Gros Ventre, Assiniboine, Pawnee, and Ute. Later they had to fight the Lakota and their allies, the Arapaho and Cheyenne. The tribes in the Blackfoot Confederacy and the Lakota-Cheyenne-Arapaho alliance became their greatest enemies.
The Crow were generally allies with the northern Plains tribes of the Nez Perce, Kutenai, Shoshone, Kiowa and Kiowa Apache. They were also allies with the Flathead, although sometimes they had conflicts with them. The powerful Iron Confederacy ("Nehiyaw-Pwat"), an alliance of northern plains Indian nations developed as enemies of the Crow. It included the Plains Cree and Assiniboine peoples, and later included the Stoney, Saulteaux, Ojibwe, and Métis.
When a large number of white Americans arrived, the Crows were fighting enemies who greatly outnumbered them. In the 1850s, a boy named Plenty Coups had a vision. The tribal elders said the dream meant that the whites would become dominant over the entire country, and that the Crows would need to remain friendly with the whites.
By 1851, the Lakota and Cheyenne were fighting the Crow for their hunting lands. They took over the eastern hunting lands, and pushed the Crow to the west and northwest upriver on the Yellowstone. After about 1860, the Lakota Sioux had all the former Crow lands. They threatened Americans who were moving into these areas.
The Crow signed the Fort Laramie Treaty of 1851 with the United States. This treaty recognized a large area around the Big Horn Mountains as Crow lands. But the Cheyenne and Lakota Sioux were still moving westward and pushing the Crows.
After Red Cloud's War (18661868) between the Lakota Sioux and the United States, the Lakota controlled territory from the Black Hills to the Big Horn Mountains. Bands of Lakota Sioux and Northern Cheyenne began to hunt and raid in ancestral Crow territory.
Crow warriors fought for the US Army in the Great Sioux War (1876–1877). This war ended with the defeat of the Sioux and Cheyenne. Some of the Sioux and their allies went to Canada, while others were removed to reservations.
The Crow had a matrilineal system. After marriage, the husband moved to the wife's mother's house. Women held a significant role within the tribe.
Like other Plains tribes, the Crow historically had three defined gender roles: male, female and "baté" (trans female / "two-spirit").
The Crow Indian Reservation is in south-central Montana. Its area is about , making it the fifth-largest Indian reservation in the United States. The 2000 census reported a total population of 6,894 on reservation lands.
The seat of government and capital of the Crow Indian Reservation is Crow Agency, Montana.
