👍noice
8 is in -8...not +8
Thanku
what is pH of 0.001M HBr
is wale method se kaise karenge
Can't we just remember the result of log i.e x.10^-y =y-log(x ) 😊
Good explanation 2:21
Thank you very much mem nice concept ❤
Nice yr ❤
TQ mam u explain it very well ❤
How can u write 10power 8 o.1*10power 7 can u explain
1×10⁸ can be written as 0.1×10⁷ by simply deducting 10 from 10⁸ and dividing it by 1 (1/10=0.1) .
Mam apki insta id kya hau
Mam hr time NTP ki value= 25 degree hi hogi ?
Thank you so much ma'am 💖💖
Thanks mam i am doing this question in 11th class
But mam the pH of water is balanced by pOH of water so how can we count the [H]+ as it is balanced by hydroxyl ions
Since [H]+ is an acid and [OH]- is a base, So pH + pOH = 14; & [H]+ = 10^-pH
Mam Thank you very much We were given the assignment And it was really helpful
Mam H. E ka matlab kya hai
Heating Effect
@@l.aclasses8078 thank you mam
Im doing this question in 11th and i wonder that u are doing it in bsc2
