Now let's see how to make 1 N and 1M H2SO4 from 98% concentrated H2SO4 . This calculation varies with concentration of H2SO4. Because density varies with concentration of H2SO4 . Now we are having density 1.84 for 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then first find out density of it then put that value in below formula instead of 1.84 H2SO4 is liquid, so at first we need to convert H2SO4 molecular weight (gm) into volume (ml) let's use formula density = mass / volume volume = mass of HCl / density 98.08 / 1.84 V = 53.30 ml Here we are making 1M and 1N H2SO4 from 98% concentrated H2SO4. If you are going to use less concentrated H2SO4 then use that percentage value in below formula rather than 98%. Let's use formula 1M H2SO4 (98%) = 53.30 ml [ V ] 100% ...
We all know we can use ice removal vehicle's To make clear roads. We pick that option when amount of ice is very large.
But when amount of ice is very less then we can use two easy way.
1) sodium chloride : we can spread that sodium chloride on ice. That sodium chloride will absorbe all moisture which is present on that ice then salt plus ice water solution will form called brine .that brine has some endothermic properties. Endothermic properties means heat absorption properties .
That brine solution will absorbe heat and make surrounding weather cool. But ice will melt due to the absorption of heat.
2) By using sand:
Sand has no properties just like sodium chloride eventhough sand is usefull to remove ice from road.
When we spread sand on road, it create friction between car tyres and road ,that is plus point .
Due to the car velocity sand particals get velocity and that accelerated sand fall on ice crystals. And create disturbance to form new ice crystals.
