hey ppl sum of u said it is t3po4 ok den u say it is not a metal from group 1 but how can tht be wen u write a formula u exchng  da valency  n da valency of phosphorous is 3 n it has to be a group 1 metal to becum t3po4
pls reply
n it has to be less reactive metal because it needs only 6cm3 of the other phosphater to react completely n i wrote lithium its less ractive n der is no evidence as far as i noe tht lithium salts are soluble


n for that indicato test i wrote litmus dey only mentioned indicators
n i think ph meters are correct because it is not an indicator n dey did not ask 4 a chemical test

I am so curious to find out the answers so pls answer my following questions:

1 What was the formulae of the metal T?n how to do that

2 What will be (needed to produce/produced by the hydrolysis) of the ester
(where the 2 blanks were given)

3 What was the test to show that both lactic acid and acrylic acid contained the COOH group

I hope i'll get the answers soon
