Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater, where it is the main mineral constituent. The open ocean has about 35 grams (1.2 oz) of solids per liter of sea water, a salinity of 3.5%. Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation. Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, the Greeks, the Romans, the Byzantines, the Hittites, Egyptians, and the Indians. Salt became an important article of trade and was transported by boat across the Mediterranean Sea, along specially built salt roads, and across the Sahara on camel caravans. The scarcity and universal need for salt have led nations to go to war over it and use it to raise tax revenues. Salt is used in religious ceremonies and has other cultural and traditional significance.

Salt is processed from salt mines, and by the evaporation of seawater (sea salt) and mineral-rich spring water in shallow pools. Its major industrial products are caustic soda and chlorine; salt is used in many industrial processes including the manufacture of polyvinyl chloride, plastics, paper pulp and many other products. Of the annual global production of around two hundred million tonnes of salt, about 6% is used for human consumption. Other uses include water conditioning processes, de-icing highways, and agricultural use. Edible salt is sold in forms such as sea salt and table salt which usually contains an anti-caking agent and may be iodised to prevent iodine deficiency. As well as its use in cooking and at the table, salt is present in many processed foods. Sodium is an essential nutrient for human health via its role as an electrolyte and osmotic solute. Excessive salt consumption may increase the risk of cardiovascular diseases, such as hypertension, in children and adults. Such health effects of salt have long been studied. Accordingly, numerous world health associations and experts in developed countries recommend reducing consumption of popular salty foods. The World Health Organization recommends that adults should consume less than 2,000 mg of sodium, equivalent to 5 grams of salt per day.

This is the outline of the geography of the city of Ottawa, the capital of Canada. Ottawa's current borders were formed in 2001, when the former city of Ottawa amalgamated with the ten other municipalities within the former Regional Municipality of Ottawa–Carleton. Ottawa is now a single-tiered census division, home to 870,250 people. The city centre is located at the confluence of the Ottawa and Rideau Rivers. The Ottawa River forms the entire northern boundary of the city which it shares with the province of Quebec's municipalities of Pontiac and Gatineau. The northern boundary begins in the west at Arnprior and continues east to Rockland. The boundary then turns south in a straight line, separating the former Township of Cumberland (now in Ottawa) and the City of Clarence-Rockland. It then turns west in another straight line separating the former Township of Cumberland with the municipalities of The Nation and Russell.

It then turns south separating Russell from the former Township of Osgoode (now in Ottawa). That boundary runs south in a straight line, then turns west separating Osgoode from the municipality of North Dundas. That boundary runs west in a straight line before turning north separating Osgoode from the municipality of North Grenville. This is another straight line, running north until the Rideau River near Kemptville. The boundary follows the river upstream until almost reaching Merrickville. The boundary then runs in a northwest direction in a straight line with a number of jogs. It separates the municipalities of Montague, Beckwith and Mississippi Mills from the former townships of Marlborough, Goulbourn, Huntley and Fitzroy.
