True
False
Normal sea water is slightly basic, with an average pH of around 8.1. This means it is not acidic but rather alkaline. The pH level can vary slightly depending on location and other factors.
Yes, it's normal frozen water or normal sea water.
The red sea is normal salt water sea.
Sea water contains a large no. of salts dissolved in it making its pH 8.0 to 8.3 which means it is basic.
A sea water ice cube would melt faster than a normal ice cube because sea water has a lower freezing point due to the presence of salt. This means that it would require less heat energy to melt the sea water ice cube compared to a normal ice cube.

Sea water is easier to float in, but wave make it harder to swim in.
Normal saline has approximately 9,000 ppm (parts per million) of dissolved salt, while sea water typically has around 35,000 ppm of dissolved salt. Sea water is therefore more concentrated in salt compared to normal saline.
Sea water has a higher boiling point than water, meaning that it will have to be heated more then pure water to boil. This temperature depends on the concentration of the salt in the salt water. The boiling point of normal water at normal pressure is 100C/212 F while for sea water it is 2 C higher or more depending on the salt concentration/impurities in the sea water. The difference in the boiling points would be 2 C or greater.
Seawater is slightly basic due to the presence of dissolved salts that contain ions such as bicarbonate and carbonate which can act as weak bases. The pH of seawater is typically around 8.0, making it slightly alkaline.
Yes, sea water would change color with red litmus paper because sea water is basic. Under basic, or alkaline, conditions, red litmus paper turns blue. Being between the pH range of 7.5 and 8.4 (between 7 and 14 marks basic conditions), sea water is basic and, therefore, the red litmus paper will change color.
Because it is the salt found in the sea water. And the life started in the sea (ocean)
