Valency of P is 5, and valency of O is 2, in phosphate 4 o atom are there so total valency O2 is 4*2=8 and net valency of phosphate will be 8-5=3 so PHOSPHATE ion has 3 valency.

valence of phosphate ion is 3- is as follows we know that valency of P is 5 valency of O is 2 In phosphate 4 O atoms are there so total valency of oxygen will be:4*2=8 Net valency on phosphate will be:8-5=2 This is the reason phosphate is represented as PO43-

Phosphate formula is PO4, here oxygen valancy is -2 so 4x2=-8, phosphate can exist in +5 oxidation state, so that here phodphate valancy is -3.

H3PO3. See, the valency of phosphate is 3 because it can donate 3 electron from its outer most shell. Refer to the SPDF system in NCERT

Respected tutors! I asked a question some time ago.My goal of asking question ,even after myself being a tutor, is to get clear with not so intuitive concepts, which i find intriguing. Q.What is the change in kinetic energy(ies) of body(ies) after collision of 2 moving bodies; you can take inelastic or elastic collision. 1- Remains same 2-Decreases 3-increases 4-any other possibilty All answers with 'decrease' options are correct, either elastic or inelastic collision. you can take any example and check. Q.Just think can KE be zero after collision? - this time its a bit more intuitive. Thanks.
it should remains same.. but if friction is taken into consideration then decreases would be the right option.

Dear friends, Please correct me in case I am wrong. I your opinion , what should be the maximum number of students in a coaching class, so that each student can have maximum dedicated time from the attending teacher in the classroom. In present days, cost and time of coaching / tuition matters a lot . The same will be demontrated by the following two examples : Example 1 : Suppose a student pays Rs. 4000/= per month ( 26 days in a month , excluding Sundays ), One hour per day , number of student is only one, then cost of coaching per minute works out to (Rs. 4000/=X 1 Student )/(26 days X 60 min/day ) = Rs.2.56 per min. cost and he will get dedicated time of 60 min. each day to carry on his studies. Example - 2 : Suppose a student pays Rs. 2000/= per month ( 26 days in a month , excluding Sundays ), One hour per day , number of student is 30 in a class, then cost of coaching per minute works out to (Rs. 2000/=X 30 Students in a coaching class ) / (26 days X 60 min/day ) = Rs.38.46 per min. cost and he will get dedicated time of only two min. each day for his studies. The above examples shows that though the monthly fees paid by each student is just half ( Rs. 2000/= see example -2 ) in case of classroom type of coaching as compared to the individual coaching ( Rs. 4000/= see example - 1 ), but on the other side cost of coaching per min. based on true dedicated time is 15 times higher in case of classroom type coaching with mass students than single student coaching. These can be however extrapolated for any number of students in a coaching class. As a result the speed of learning process of a student will be about fifteen times slower in classroom type coaching having mass students in a class ignoring the other factors. However, it may be the choice of the students and parents which option is better for them ? Regards, Sudhansu bhushan Roy.
Sir your calculations are excellent. I would like to add few things. 1. It depends on the student / parents choice at the end. 2. It never implies that effective attention to a student is 2-3 mins, so...
