Eating too much salt can cause kidney disease Kidneys Your body removes unwanted fluid by filtering your blood through your kidneys. Here any extra fluid is sucked out and put into your bladder to be removed as urine. To do this, your kidneys use osmosis to draw the extra water out of your blood. Eating salt raises the amount of sodium in your bloodstream and wrecks the delicate balance, reducing the ability of your kidneys to remove the water.

Certain objects made of metal -- like boat engines -- spend a lot of time submerged in saltwater and they can corrode quickly. Simple maintenance keeps corrosion at bay. Once the metal is dry, use a marine paint or oil sealant to cover the metal completely.

To prevent electrochemical corrosion, consider a galvanized zinc coating or sacrificial cathodes. Saltwater and Metal The combination of moisture, oxygen and salt, especially sodium chloride, damages metal worse than rust does.

This combination corrodes, or eats away at, the metal, weakening it and causing it to fall apart. Saltwater corrodes metal five times faster than fresh water does and the salty, humid ocean air causes metal to corrode 10 times faster than air with normal humidity.

Bacteria in ocean water also consumes iron and their excretions turn to rust. Electrochemical Corrosion One form of corrosion that occurs when metal and saltwater get together is called electrochemical corrosion. Metal ions dissolve in water and saltwater conducts electricity and contains ions, which attract ions from other compounds.

During electrochemical corrosion, electrons from other compounds are attracted to the metallic ions. Saltwater attacks the metal and corrosion occurs. Sciencing Video Vault Anaerobic Corrosion As the second type of corrosion that occurs when metal is exposed to saltwater for an extended period, anaerobic corrosion leaves deposits that contain sulfates and surround the metal as it sits in saltwater; Hydrogen sulfide is produced which then corrodes metals.

At the same time, bacteria grow in the saltwater which used the hydrogen to corrode the metal as well. Between the ions, sulfates and bacteria, metal is attacked from all angles when it is in saltwater. Preventing Corrosion To prevent the corrosion of metal in saltwater, rinse the metal completely in fresh water after removal from saltwater.

Dry the metal thoroughly, especially in crevices and pockets where saltwater lingers. To store metal that regularly sits in saltwater, keep the metal submerged completely in oil, antifreeze or kerosene. These measures can keep boat hulls, engines and other seafaring metals from corroding.

Saltwater corrodes metal five times faster than fresh water does and the salty, humid ocean air causes metal to corrode 10 times faster than air with normal humidity. Bacteria in ocean water also consumes iron and their excretions turn to rust. So when we say that salt water is more dense than regular water it means that there is more mass in a certain volume of the salt water than there is in the same volume of normal water. When you add table salt (sodium chloride, NaCl) to water, the salt dissolves into ions, Na + and Cl -. Since the kidneys are geared to maintain a fixed proportion of sodium to water in the blood, excess salt in the body means excess water too and hence excess weight of the body. vi. Worsening of Oedema: Salt makes oedema worse and should be avoided in all oedematous states whether due to liver, kidney or endocrine diseases. vii.

The result is a higher blood pressure due to the extra fluid and extra strain on the delicate blood vessels leading to the kidneys. Effect on Kidneys: Excess salt puts a heavy burden on kidneys because they have to work harder to remove the excess salt.

Hence they may gradually weaken.

Hence they may gradually weaken. Kidneys can’t remove more than gm of salt per day. The cube that salt has not been added to, has a melting point $0~\mathrm{^\circ C}$ and so if we measure its temperature during melting it will remain zero until all ice is molten.

That ice cube to which we have added salt, the salt that is added lowers the melting and freezing points of water because it lowers the vapor pressure of water.

vii. If you have acne, salt water has a side effect that actually heals and improves the look of acne scars. Salt water removes the excess oil from skin.

One of the most important parts of using salt water as an acne treatment is rinsing off any salt water afterwards.
