How do oh levels determine acidity or basic out of a given...

Transcript

00:01 Hello student the question.

00:01 What is the concentration of oh in the lime water? the first part is going to find out the oh value ph value that is what i don't hear my and which is given here the value of i don't know and that is 3 .98 multiplied by 10 k power minus 13 we are going to calculate the oh iron firstly that is 10 k power minus 14 divided by that is 3 .98 multiplied by 10 k power minus 13 that is to what 1 by 3 .98 multiplied by 10 key power minus 1 that means p -o -h is equal to 1 .59.

00:39 That means it is basic in nature.

00:42 Basic according to the options, acid, basic or neutral, this is basic in nature.

00:47 Now the second part of this question which is here we are going to find out the ph, that is what ohn here which is given here 10 key power minus 8 molar and h -i -n we are going to calculate that is 10 k power minus 14 according to the formula that is ph that is equal to that is p -o -h is equal to tank of power minus 14 that is divided by what tank of power minus 48 and that is what here which is tank power minus 6 it means that ph is equal to that is 6 means acidic in nature that is not a ph that is h -ion or h -ion concentration and that is the answer the third point which is here given here and third is we are going to hydronium ion that is equal to 1 .6 multiply by tank of power minus 6 molar and we are going to calculate oha and concentration value that is 1 by 1 .6 multiplied by watt multiply by tank of minus 8 that means what here over time concentration that is equal to 0 .6 to 5 multiply by tanker power minus 8 molar that means what p o h that is equal to 8 minus 0 .2 that is means p o h is equal to p o h is equal to 7 .8 now another part of this question means that is in basic in nature that is in basic nature now another part of this question that is what here that is 4 point o -h giant concentration which is given here's 3 .16 multiply by 10 k power minus 11 that is 1.

02:29 Or h -ion concentration that is equal to tank -power minus 14 divided by 3 .6 multiplied by tank -power minus 11 that is equal to 1 by 3 .6 multiplied by tank -power minus 3.

02:41 It means that what here p .h is equal to 3 minus 0 .5 means 2 .5.

02:48 That means p .h is equal to 2 .5...
